Synthesis of copolymer from acryloyl chloride graft on polyvinyl alcohol

Graft reaction of the acryloyl chloride on polyvinyl alcohol in dimethyl sulfoxide was studied.The effect of concentration,temperature,time on grafting rate were discussed.The results showed that the best grafting condition:n(PVA) ∶n(acryloyl chloride)=1 ∶1,at 50 ℃ for 2 h.The graft copolymerization was analysed by UV,FTIR and 1H NMR.
