Available in PDF, EPUB and Kindle. Book excerpt: Summarizes the current state of the art concerning the effect of organization of monomers on the polymerization process. Some of the techniques covered that bring about such ordering include thermotropic and lyotropic liquid crystalline media, gas-water and gas-solid interfaces, micelles and microemulsions. Potential applications range from novel composite media to biopolymer synthesis. Annotation copyright by Book News, Inc., Portland, OR

This book was released on 1990 with total page 31 pages. Available in PDF, EPUB and Kindle. Book excerpt: The synthesis and living cationic polymerization of 5-((4-cyano-4'- biphenyl)oxy)pentyl vinyl ether (6-5)and 7-((4-cyano-4'biphenyl)oxy)heptyl vinyl ether (6-7) are presented. The influence of molecular weight on the mesomorphic behavior of poly(6-5) and poly(6-7) is discussed and compared to that of 5-((4- cyano-4'-biphenyl)oxy)pentyl ethyl ether (8-5) and 7((4-cyano-4'-biphenyl)oxy) heptyl ethyl ether (8-7) which are models of the monomeric structural units of poly(6-5) and poly(6-7). Both (8-5) and (8-7) exhibit a monotropic nematic mesophase.

Synthesis and Mesomorphic Behavior of Poly(2-(4-Cyano-4'- Biphenyl)oxy)ethyl Vinyl Ether-co-8-(4-Co-4'-Biphenyl)oxy)octyl Vinyl Ether). written by and published by . This book was released on 1990 with total page 28 pages. Available in PDF, EPUB and Kindle. Book excerpt: The synthesis and characterization of poly 2-(4-cyano-4 '-biphenyl) oxy ethyl vinyl ether poly(6-2), poly 8-(4-cyano-4'biphenyl)oxyocctyl vinyl ether poly(6-8) and poly (6-2-co6-8) X/Y (where X/Y is the molar ratio of the two monomeric structural units) with degrees of polymerization of about 10 and narrow molecular weight distribution are described. Both homopolymers and copolymers were prepared by living cationic polymerization and copolymerization of 6-2 and 6-8. During the first heating scan poly(6-2) presents an inverse monotropic s sub c mesophase. During subsequent heating and cooling scans, this polymer is amorphous regardless of the thermal history of the sample. Poly(6-8) exhibits an enantiotropic s sub a mesophase. Both during the first and subsequent haeting and cooling scans, the phase diagram which plots the dependence of mesomorphic transition temperatures as a function of copolymer composition presents a discontinuity.

Influence of Molecular Weight on the Phase Transitions of Poly(Omega-((4-Cyano-4'-Biphenyl)oxy)alkyl Vinyl Ethers)s with Nonyl and Decanyl Alkyl Groups written by and published by . This book was released on 1990 with total page 36 pages. Available in PDF, EPUB and Kindle. Book excerpt: The first goal of this series of publications is to provide a complete elucidation of the influence of molecular weight on the phase behavior of poly omega-(4-CYANO-4'-BIPHENYL)OXYaklyl vinyl ether s containing alkyl groups from ethyl to undecanyl. The goal of this paper is to describe the synthesis and living cationic polymerization of the last two monomers from this series, i.e., 9-(4-CYANO-4'-BIPHENYL)OXYnonyl vinyl ether (6-9) and 10-(4-CYANO- 4'-BIPHENYL)OXYdecanyl vinyl ether (6-10). The influence of molecular weight on their phase transitions will be discussed by comparison to that of 9-(4-CYANO- 4'-BIPHENYL)OXYdecanyl ethyl ether (8-10) which represents the model compounds of the monomeric structural units of poly (6-9) and poly (6-10). Then, the mesomorphic behavior of poly?w-(4-CYANO-4'-BIPHENYL)OXYalkyl vinyl ether s with alkyl groups containing from two to eleven methylenic units will be comparatively discussed at four different degrees of polymerization: 30, 23, 13 and 4. The implication of different phase transitions at various molecular weights on the molecular design of novel macromolecular architectures based on side charm liquid crystalline polymers is briefly discussed.

Influence of Molecular Weight, Interconnecting Unit and Substituent on the Mesomorphic Behavior of Polymers with Laterally Attached Mesogens written by and published by . This book was released on 1992 with total page 50 pages. Available in PDF, EPUB and Kindle. Book excerpt: Norbornene derivatives containing laterally attached 2,5-bis(4'-n- alkoxybenzoyl OXY) mesogens were polymerized by controlled ring opening metathesis polymerization to provide polymers in high yield with 5-100 repeat units and narrow molecular weight distributions. Monomers with n>l displayed monotropic or enantiotropic nematic mesophases. All polymers displayed enantiotropic nematic mesophases regardless of the spacer, molecular weight or length or the n-alkoxy substituent. Constitutional isomers of poly(5-carbo(2', 5'-bis-4(methoxybenzoyloxy)benzyloxy)bicyclo(2.2.1)hep t-2-ene)s containing laterally attached mixed phenylester/benzylester units are amorphous. Side chain liquid crystal polymers (SCLCPs), living ring opening metathesis polymerization.
