Stereoregular polymer and monomer thereof and process for production of both

摘要

An ester derivant having a crystal structure in which the molecules in two adjacent molecule planes are antiparallel is created from a carboxylic acid having carbon-carbon double bond and a compound having a functional group that can react to a carboxyl group of the carboxylic acid. The crystal of the ester derivant is then subjected to light irradiation or heating.
