【Abstract】 The successful grafting of methylmethacrylate （MMA） onto silk fibers involves the creation of free radicals on the backbones of silk fibers, In the present paper, we have reported the regularities of grafting copolymerization of MMA onto silk fibers by quinquivalent vanadium ion(V⁵⁺) in an aqueous medium. The graft yield increases significantly by increasing monomer concentration. With the increasing of V⁵⁺ concentration, the graft yield increases but beyond 0.005M it decreases. The graft yield also increases with the increasing of H₂SO₄ concentration but beyond 0.55M it decreases, The rate of grafting is considerably influenced by reaction temperature. A suitable over-all rate equation of grafting copolymerization has been derived.更多还原
