The results show that chain transfer constant depends on reaction temperature and solvent. High temperature favors graft copolymerization, and enhances the efficiencyofgrafting.
试验结果表明提高反应温度和选择适当溶剂可以使链转移常数增大,有利于接枝反应的进行,提高接枝效率。

The effect of the molar ratio of glycolide to starch and reaction time on the grafting degree, grafting efficiency and monomer conversion was discussed.
讨论了原料配比和反应时间对共聚物接枝率(G)、 接枝效率(E)和单体转化率(C)的影响。
