摘要：

Block copolymers of poly(styrene-b-methyl methacrylate), poly(styrene-b-n-butyl methacrylate) and poly(methyl methacrylate-b-styrene) have been prepared via chemical reactions. A new polymeric peroxycarbamate is synthesized by reacting equimolar amounts of an aliphatic diisocyanate with a dihydroperoxide. This compound is an effective polymerization initiator, and is used to prepare active prepolymers containing fragments of polymeric peroxycarbamate. A second vinyl monomer is then incorporated to produce various block copolymers. Styrene contents, intrinsic viscosities and chemical and mechanical properties of the copolymers were determined.
