Synthesis and Study of Polymers Using Complex Monomers

Abstract
In this paper the synthesis of five new types of semiflexible thermotropic polymers is described. Complex monomers are used in order to obtain polymers with a regular structure. Of the twelve polymers obtained, one does not exhibit mesomorphic properties, while of the remaining eleven, ten show nematic and one smectic C and nematic phases. A comparative study is made of the four different methods of polymerization: Interfacial Polycondesation, Low Temperature Solution, High Temperature Solution and Melt Transesterification.
