明胶与丙烯酸甲酯在^(60)Co辐照下的接枝聚合反应

Tentative studies on the graft copolymerization of glutin and methacrylate in radiation

利用辐射源60Co辐照引发明胶与丙烯酸甲酯接枝聚合反应,接枝聚合物IR谱显示,1560cm-1处有明胶酰胺基的特征吸收,1760cm-1处强吸收峰则为丙烯酸甲酯单元的羰基特征红外吸收,从而证明了明胶与丙烯酸甲酯接枝的存在.进一步研究了不同辐照剂量、明胶与丙烯酸甲酯不同配比对接枝聚合物产量的影响.

Radiation source ()^(60)Co radiate to induct reaction of graft copolymerization between glutin and methacrylate (MA). IR atlas of reaction of graft copolymerization show characteristic absorb of glutin acyl-amidocyanogen appear in (1 560) cm^(-1) and strong absorb in (1 760) cm^(-1) is characteristic absorb of MA. It proves to occur to graft copolymerization reaction between glutin and MA. This papers studies different radiation dosages and different proportions between glutin and MA to graft polymerization reaction influence.
