摘要：

The sequential block copolymerization product of styrene with mixture of ethylene and propylene was fractionated by successive extraction with suitable solvents. The isolated iPS-b-Poly(E-co-P) block copolymer (20%similar to 30% content in total), which is soluble in butanone or chloroform was characterized by C-13 NMR, FTIR, WAXD, DSC and TEM etc.. This kind of copolymers containing iPS segment are semi-crystalline diblock copolymers with special microphase-separation structure.
