✦ Synopsis
The polymerization of p-propiolactone (BPL) induced by radiation and by radical catalysts, the influences of radical inhibitors and electron acceptors on this polymerization, and graft copolymerization were studied. It was found that BPL wm polymerized by benzoyl peroxide in the presence of electron acceptors such as maleic anhydride and acrylonitrile. This polymerization method was applied to graft copolymerization. The electron donative trunk polymer containing ether groups was heated with benzoyl peroxide or was irradiated by y-rays from Cow in the presence of maleic anhydride as the electron acceptor. j3PL was added subsequently to form the graft copolymer.
