Book excerpt: While books have been written on many topics of Polymer Science, no compre hensive treatise on long chain branching has ever been composed. This series of reviews in Volume 142 and 143 of Advances in Polymer Science tries to fill this gap by highlighting active areas of research on branched polymers. Long chain branching is a phenomenon observed in synthetic polymers and in some natural polysaccharides. It has long been recognized as a major mole cular parameter of macromolecules. Its presence was first surmised by H. Stau dinger and G. V. Schuh (Ber. 68, 2320, 1935). Interestingly, their method of iden tification by means of the abnormal relation between intrinsic viscosity and molecular weight has survived to this day. Indeed, the most sophisticated method for analysis of long chain branching uses size exclusion fractionation with the simultaneous recording of mass, molecular weight and intrinsic visco sity of the fractions. In the 1940s and 1950s, random branching in polymers and its effect on their properties was studied by Stockmayer, Flory, Zimm and many others. Their work remains a milestone on the subject to this day. Flory dedicated several chapters of his "Principles of Polymer Chemistry" to non linear polymers. Especially important at that time was the view that randomly branched polymers are inter mediates to polymeric networks. Further developments in randomly branched polymers came from the introduction of percolation theory. The modern aspec ts of this topic are elaborated here in the chapter by W. Burchard.

Available in PDF, EPUB and Kindle. Book excerpt: This 2-volume set includes extensive discussions of scattering techniques (light, neutron and X-ray) and related fluctuation and grating techniques that are at the forefront of this field. Most of the scattering techniques are Fourier space techniques. Recent advances have seen the development of powerful direct imaging methods such as atomic force microscopy and scanning probe microscopy. In addition, techniques that can be used to manipulate soft matter on the nanometer scale are also in rapid development. These include the scanning probe microscopy technique mentioned above as well as optical and magnetic tweezers.

This book was released on 2014-04-08 with total page 134 pages. Available in PDF, EPUB and Kindle. Book excerpt: Lianwei Li's Ph.D. thesis solves a long-standing problem in polymer physics: how does a hyperbranched chain pass through a cylindrical pore smaller than its size under an elongational flow field? The question was asked by the Nobel Laureate, the late Professor de Gennes in the 70s but has never been seriously addressed through real experiments. This thesis outlines how Lianwei Li developed a novel polymerization strategy using a seesaw-type macromonomer to prepare a set of "defect-free" hyperbranched chagins with different overall molar masses and controllable uniform subchain lengths. The author then unearthed how the critical (minimum) flow rate at which a hyperbranched chain can pass through the pore, is dependent on the overall molar mass and the subchain length. The experimental results give a unified description of polymer chains with different topologies passing through a small cylindrical pore, which enables us to separate chains by their topologies instead of their sizes in ultrafiltration. In addition, this research also reveals how the chain structure of amphiphilic hyperbranched block and graft copolymers affect their solution properties, including the establishments of several classic scaling laws that relate the chain size and the intrinsic viscosity to the overall molar mass and the subchain length, respectively. This work has led to numerous publications in high-impact peer-reviewed journals.

Book excerpt: The last two decades have seen a number of significant advances in the methodology for evaluating the molecular weight distributions of polydispersed macromolecular systems in solution at the molecular level. This reference presents reviews on the progress in different analytical and characterization methods of biopolymers. Readers will find useful information about combinations of complex biopolymer analysis such as chromatographic or membrane based fractionation procedures combined with multiple detectors on line (multi-angle laser light scattering or MALLS). Key topics include: • refractive index, UV-Vis absorbance and intrinsic viscosity detection systems, • advances in SEC-MALLS (size exclusion chromatography coupled to multi-angle laser light scattering) and FFF-MALLS (field flow fractionation coupled on line to MALLS), • HPSEC-A4F-MALLS, matrix-assisted laser-desorption ionization (MALDI) • electrospray ionization (ESI) mass spectrometry • nuclear magnetic resonance (NMR) spectroscopy This reference is intended for students of applied chemistry and biochemistry who require information about biopolymer analysis and characterization.

Book excerpt: Since their inception more than 2.5 years ago, photon correlation techniques for the spatial, temporal or spectral analysis of fluctuating light fields have found an ever-widening range of applications. Using detectors which re spond to single quanta of the radiation field, these methods are intrinsically digital in natnre and in many experimental situations offer a unique degree of accuracy and sensitivity, not only for the study of primary light sources themselves, but most particularly in the use of a laser-beam probe to study light scattering from pure fluids, macromolecular suspensions and laminar or turbulent flowing fluids and gases. Following the earliest developments in laser scattering by dilute macro nl01ecular suspensions, in , ... hich particle sizing was the main aim, and the use of photon correlation techniques for laser-Doppler studies of flow and tnrbuence. both of which areas were the subject of NATO ASls in Capri, Italy in 19;:3 and 19;6. significant advances have be('n made in recent years in many other areas. These were reflected in the topics covered in this NATO Advanced Research Workshop, which took place from August 2;th to 30th, 1!)!}6, at the Jagiellonian University, Krakow, Poland. These in cluded ('xperimental techniques. statist.ics and data reduction, colloids and aggregation, polymers, gels, liquid crystals and mixtures, protein solutions, critical pllf'nomena and dense media.

Book excerpt: Between June 6-10, 1988, the Third Chemical Congress of North America was held at the Toronto Convention Center. At this rare gathering, fifteen thousand scientists attended various symposia. In one of the symposia, Professor Pierre-Gilles de Gennes of College de France was honored as the 1988 recipient of the Amer ican Chemical Society Polymer Chemistry Award, sponsored by Mobil Chemical Corporation. For Professor de Gennes, this international setting could not be more fitting. For years, he has been a friend and a lecturer to the world scientific community. Thus, for this special occasion, his friends came to recount many of his achievements or report new research findings mostly derived from his theories or stimulated by his thoughts. In this volume of Proceedings, titled New Trends in Physics and Physical Chemistry of Polymers, we are glad to present the revised papers for the Symposium and some contributed after the Symposium. In addition, we intend to include most of the lively discussions that took plaGe during the conference. This volume contains a total of thirty-six papers divided into six parts, primarily according to the nature of the subject matter: • Adsorption of Colloids and Polymers. • Adhesion, Fractal and Wetting of Polymers. • Dynamics and Characterization of Polymer Solutions. • Diffusion and Interdiffusion of Polymers. • Entanglement and Reptation of Polymer Melts and Networks. • Phase Transitions and Gel Electrophoresis.
