摘要：
The microstructures of both random and alternating copolymers of styrene and methacrylonitrile were investigated by high field C-13 n.m.r. spectroscopy. N.m.r. analysis of random copolymers provided information pertaining to different modes of comonomer placements along the chain. Information about the stereochemical aspects of comonomer placements (co-tacticity) was derived from the spectra of alternating copolymers. These results provided valuable information regarding the chain microstructures and the copolymerization mechanism.
