| Abstract: | In this paper, kinetics of the ~(60)Co gamma ray induced graft copoly-merization of mixture of methyl methacrylate and acrylonitrile onto wool was studiedin detail. The results shown the following functional relationship equation: R_g=k'[M]_0~(0.8)D~(0.35)The apparent activation energy and the collision frequency factor of the grafting copo-lymerization are 14. 23 kJ/mol and 278g%h~(-0.65)kGy~(0.35)mol~(-0.8)L~(0.8).,respectively. The work established that the relationship of the grafting copolymerization ratewith T, [M]_0, and D relational expression at arbitrary temperature: lnR_g=5. 63-1710 1/T +0.8 ln[M]_0+0.35 lnD. |
