Available in PDF, EPUB and Kindle. Book excerpt: Liquid crystal polymers (LCPs) have a wide range of uses, from strong engineering plastics to delicate gels for use in liquid crystal (LC) displays. For this reason, it is essential reading for materials scientists, engineers or technologists in industry, as well as research laboratories or academia. An additional indexed section containing several hundred abstracts from the Rapra Polymer Library database gives useful references for further reading.

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.

This book was released on 2012-12-06 with total page 486 pages. Available in PDF, EPUB and Kindle. Book excerpt: The subject of liquid crystals and their use in electronic displays and in non-linear optical systems has become of tremendous importance during the last decade; and the incorporation of liquid crystal units into polymeric materials has led to a group of new materials with diverse properties. Some of these properties have been utilized in new products and some have yet to be used. Much published work has appeared that deals with specific materials or particular applications, and it was felt that a book was needed to examine and explain the underlying principles governing the diverse properties of these liquid crystal polymers, LCPs. The current work describes the diverse nature of LCPs, their synthesis, characterization, properties and finally their applications. It describes the manner in which liquid crystallinity or mesomorphism occurs in small molecules, monomer liquid crystals and polymer liquid crystals. Chapter 1 gives a classification of the various ways in which the meso gens may be connected to the polymer chains. Currently, the bulk of LCP material is based on main chain or longitudinal LCPs for use in engineering applications. The side chain or comb polymers are intended for use in electronics and opto-electronic systems and as surfactants. Many other variants and possibilities exist but their properties have not yet been fully studied or used. In this respect it is hoped that the current work will indicate future possibilities as well as discussing current opinion. v Preface vi Chapters 2 and 3 describe methods of characterizing the mesophases.

This book was released on 2005 with total page 364 pages. Available in PDF, EPUB and Kindle. Book excerpt: "In order to better assign the thermotropic properties of laterally attached side-chain liquid crystalline polymers (SCLCPs), a series of model compounds, {2, 5-bis [(3' -fluoro-4' -n-alkoxyphenyl)ethynyl]phenyl}- alkanes, with spacer lengths m = 2 to 10, and 12 with n-alkoxy substituent lengths of n = 8 and n = 10 were synthezised and compared with previous results of m = 0, 1, and 11.1̕2 The thermotropic behavior of the models were analysed by differential scanning calorimetry (DSC) and polarized optical microscopy (POM). For all model compounds, only a nematic phase was observed. The isotropization temperatute decreased rapidly for the space length m = 0 to 3 and then converged toward a constant value for longer spacer lengths. Interestingly, the n = 8 model compounds were more stable, had a longer isotropization temperature, then the n=10 model compounds for m 8, but the n = 10 model compounds have a higher isotropization temperature than the n = 8 model compounds for m = 8. Ring-openning metathesis polymerization (ROMP) of achiral 5-[[[[2',5'-bis[2-(3'-fluoro-4'-decyloxyphenyl)-ethynyl]phenyl]alkyl]oxy]carbonyl]bicyclo[2.2.1]hept-2-enes were completed for a series of spacer lengths m = 3 to 10, and 12 and gave polymers with a degree of polymerization (DP[subscript n]) of 40 to 167 and polydispersity (pdi) of 1.17 to 1.38. The thermotropic behavior was studied by DSC and POM. For all achiral polymers, only a nematic phase was observed. As with the model compounds, the isotropization temperature rapidly destabilized for m = 1 to 3 and converges to a constant value for longer spacer lengths. Furthermore, there was excellent correlation between the value of athe isotropization temperature of hte models and the achiral polymers. Since the polymer with the short spacer length m = 1 was the only one with a smectic C phase, chiral poly {5-{1-[[[2'',5''-bis[2-(3'-fluoro-4'-decyloxyphenyl)ethynyl]-phenyl]ethyl]oxy]carbonyl}bicyclo[2.2.1]hept-2-ene and poly {5-{1-[[[2'',5''-bis[2-(3'-fluoro-4'-decyloxyphenyl)ethynyl]-phenyl]ethyl]oxy]carbonyl}bicyclo[2.2.1]hept-2-ene-co- 5-{[2',5'-bis[2-(3'-fluoro-4'-decyloxyphenyl-ethynyl]benzyl]oxy]carbonyl}bicyclo[2.2.1]hept-2-ene} were synthesized by ROMP and gave polymers in high yield. The homopolymer has a DP[subscript n] = 21 and a pdi of 1.13. The copolymer had a DP[subscript n] = 95.4 and a pdi of 1.36. The thermotropic behavior was studied by DSC and POM. The homopolymer showed no liquid crystallinity, just a glass transition at 38.7 °C. The copolymer was able to restablish the liquid crystallinity, however only nematic textures were present"-P. iii-v.
