摘要
本文对由 Ce^(4+)引发的、在真丝上的 MMA(甲基丙烯酸甲酯)接技共聚的反应体系,进行了研究。实验结果表明,接枝反应的速率取决于引发剂及单体的浓度,反应温度和真丝性质的差异。此外,还研究了不同种类稀土离子 Ce^(4+)和硫酸铜浓度对该反应速率的影响。
The reactive system of the graft copolymerization of methyl methacry- late onto silk fibers initiated by tetravalent ceric ions is studied in detail. The experimental.results show the rate of grafting depends on the conce ntrations of the initiator and the monomer,the temperature of reaction, and the nature of silk.The effects of different species of ceric(Ⅳ)ions and cupric sulphate on the rate of grafting are also studied.
