Lorimer and published by . This book was released on 1971 with total page 8 pages. Available in PDF, EPUB and Kindle. Book excerpt: Theoretical equations are deduced which predict that the specific refractive index of a polymer in solution is v=v(infinity)+v(0)/M(n), where M(n) is the number average molecular weight, and v(infinity)and v(0) depend on the refractive index, n(1), of the solvent, on the specific refractivity of the pure polymer, and on the specific volume of the polymer in solution. Mixtures of two polymers whose refractive increments depend on molecular weight are also considered. Methods of distinguishing the effects of polydispersity of composition from effects due to the dependence of the average v on the average molecular weight are discussed for mixtures of components whose individual properties are unknown.

This book was released on 1971 with total page 7 pages. Available in PDF, EPUB and Kindle. Book excerpt: The coefficient a(2) in the empirical equation delta n/c(s) = nu + a2c(s) for the refractive index increment of a polymer in solution is reported. Experimental values of a(2) may be used to obtain the partial derivative of v(s)/c(s), in favorable cases, and estimates of a(2) itself can be made. The dependence of a(2) on temperature and wavelength can also be found accurately. (Modified author abstract).

Download or read book Properties of Polymers written by D.W. van Krevelen and published by Elsevier. This book was released on 2012-12-02 with total page 898 pages. Available in PDF, EPUB and Kindle. Book excerpt: Properties of Polymers: Their Correlation with Chemical Structure; Their Numerical Estimation and Prediction from Additive Group Contributions summarizes the latest developments regarding polymers, their properties in relation to chemical structure, and methods for estimating and predicting numerical properties from chemical structure. In particular, it examines polymer electrical properties, magnetic properties, and mechanical properties, as well as their crystallization and environmental behavior and failure. The rheological properties of polymer melts and polymer solutions are also considered. Organized into seven parts encompassing 27 chapters, this book begins with an overview of polymer science and engineering, including the typology of polymers and their properties. It then turns to a discussion of thermophysical properties, from transition temperatures to volumetric and calorimetric properties, along with the cohesive aspects and conformation statistics. It also introduces the reader to the behavior of polymers in electromagnetic and mechanical fields of force. The book covers the quantities that influence the transport of heat, momentum, and matter, particularly heat conductivity, viscosity, and diffusivity; properties that control the chemical stability and breakdown of polymers; and polymer properties as an integral concept, with emphasis on processing and product properties. Readers will find tables that give valuable (numerical) data on polymers and include a survey of the group contributions (increments) of almost every additive function considered. This book is a valuable resource for anyone working on practical problems in the field of polymers, including organic chemists, chemical engineers, polymer processers, polymer technologists, and both graduate and PhD students.
