淀粉——苯乙烯接枝共聚物的研究(Ⅰ)

Study on Graft Polymer of Starch and Styrene(Ⅰ)

本文以淀粉和苯乙烯为基本原料，经接枝共聚制备生物降解性ＰＳ母料，并讨论了原料配比、反应温度及反应时间等因素对产品性能的影响。结果表明：最佳原料配比为淀粉与苯乙烯之比为１∶１，反应温度为６０℃，反应时间为８ｈ。

With starch and styrene as basic materials ,the biodegradabic PS mather materiais was prepared by graft copolymerization.The effect of mole ratio,temperature and time of reactants on product property were discussed as well.The result obtained shows that the optimum starch:styrene is 1∶1,temperature of reactants is 60℃,time of reactants is 8 hours.
