OPTICAL ANISOTROPY OF STEREOISOMER MOLECULES OF POLYSTYRENE AND POLY-p-METHYLSTYRENE

摘要

The dependence of the optical anisotropy of chain molecules on their stereoregularity, established for fractions of polymers of the methacryl series [1,2], has been discovered for the first time in an investigation of an unfractionated sample of polystyrene [3] in this work, these investigations were conducted in greater detail, using a series of fractions of isotactic polystyrene (PS). The primary purpose of these investigations was to elucidate the question of the possibility of influence of molecular weight on the degree of microtacticity of various components-of a poly-molecular sample of polystyrene.
