Abstract

The inlluence of polymerization time on the selective amomc polymerization of α C=C double bond in 2

3-epoxypropyl methacrylate (EPMA) has been investigated．Meanwhile．the block copolymer of EPMA and methyl methacrylate (MMA)has alsobeen prepared．It is found that with the polymerization proceeding

the conversion of EPMA was going up

Mn becoming larger

but the molecular wdght distribution did notchange．The poly (EPMA)s produced are of very narrow molecular weight distributions(Mn/Mn≤1．02) and carry an epoxy group on their each repeating unit quantitatively．The block copolymers also possess narrow molecular weight distributions and the massratio of MMA to EPMA determined by NMR measurement is in good agreement、withdesigned value．
