Three‐armed , optically active star polymers (1) with C 3 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.
