Abstract

The attachment of mesogens as end groups to hyperbranched polyglycerol (degree of polymerization 22-45; see schematic representation, the rigid mesogens are shown as rods and the flexible alkyl chains as lines) leads to liquid crystalline polymers with narrow polydispersity, whose liquid crystalline behavior is induced by the mesogenic end groups only.

摘要

将介晶基团作为端基连接到超支化聚甘油上（聚合度为22 - 45；见图例说明，刚性介晶基团用棒表示，柔性烷基链用线表示），可得到具有窄多分散性的液晶聚合物，其液晶行为仅由介晶端基诱导产生。
