Optically Active, Isotactic Homopolymers ofα-Olefins with Main-Chain Chirality and the First Preparation of Optically ActiveC3-Symmetrical Polymers

Abstract

Three-armed, optically active star polymers (1) with C3 symmetry can be prepared from enantiomerically pure isotactic poly(methyl methacrylates) containing one reactive amino end group. Three such chains are coupled to 1,3,5-benzenetricarbonyl chloride. These polymers, especially if transformed in helical stereocomplexes, possess remarkably high optical rotation.
