説明

The polymerization of p-isopropenyl phenol (IPP) and its copolymerization with various vinyl and diene monomers were investigated at 60°C by using 2, 2′-azobisisobutyronitrile as a radical initiator. IPP, obtained by thermal decomposition of 2, 2-bis (4-hydroxyphenyl) propane, melts at 85°C and is needlelike crystals (from n-hexane). The radical copolymerization was carried out with acrylonitrile, methyl and ethyl acrylates, methyl methacrylate, styrene, isoprene, butadiene, and vinyl acetate. The copolymerization reaction did not proceed in the aerial atmosphere, whereas no induction period was observed in degassed condition. The analysis of copolymer composition showed that the copolymers of IPP with acrylonitrile and methyl acrylate are highly alternating. However, neither homopolymer nor copolymer was obtained from the copolymerization system of IPP with vinyl acetate. From the monomer/copolymer composition curves, the monomer reactivity ratios and Q and e values of IPP were calculated.
