The compatibility and crystallization behaviour of the mixtures of poly(tetrahy-drofuran-methyl methacrylate)diblock copolymer(PTHF-b-PMMA) with polyvinyl chloride has been studied. We found that the compatibility of these blends, in which there is special interaction between the homopolymer and the PMMA block of the copolymer, is much better than that of the AB/A type blends; and that the crystalli-zation rate and crystallinity of PTHF microdomain changed greatly due to the swollen by PVC homopolymer. In this paper, these changes in cryatallization are well explained according to the theories of block copolymer blends and the density gradient moldel presented by JIANG Ming.
