摘要:
An optically active acetylene polymer which is obtained by polymerizing an optically active form of 1-[dimethyl(10-pinanyl)silyl]-1-propyne which is represented by the following formula (I) and has a weight-average molecular weight of from 10,000 to 1,000,000, a membrane comprising this optically active acetylene polymer as the main component and a method for optically resolving a mixture of optical isomers by using this membrane: ##STR1##
