摘要

New liquid-crystalline symmetric triblock copolymers ABA, in which central LC block B is poly(p-(6-acryloyloxycaproyloxyphenyl)-p-methoxybenzoate and blocks A are amorphous blocks of polyvinylpyridine, whose units are able to form various types of noncovalent chemical bonds, are synthesized. The phase behavior of the triblock copolymers is studied, and the type of their microphase-separated structure is ascertained. It is shown that the composition of the triblock copolymers affects the morphology of their thin films.
