Monomer unit, chemical geometric

The properties of polymers are strongly influenced by details of the chain structure. The structural parameters that determine properties of a polymer include the overall chemical composition and the sequence of monomer units in the case of copolymers, the stereochemistry or tac-ticity of the chain, and geometric isomerization in the case of diene-type polymers. [Pg.520]

The detailed analysis of the structure, temperature behavior and phase as weUl as relaxational transitions of two representatives of thermotropic LC copolyesters with a statistical sequence of monomers in chains shows the strong dependence of their phase composition on the chemical stmcture of monomeric units. One of the most important factors appears to be the geometrical dimensions of the monomeric groups, from which the chain of copolymer is constructed jfrom, and the presence (or absence) of relatively large side substituents. [Pg.300]
