降解天然橡胶胶乳与甲基丙烯酸甲酯共聚的研究

Copolymerization of Methyl Methacrylate Monomer into Degraded Natural Rubber Latex

研究不同降解程度的天然橡胶胶乳与甲基丙烯酸甲酯（ＭＭＡ）共聚反应，找到了一种适用于降解胶乳与ＭＭＡ共聚混合物的分离方法，发现随着降解时间的增长，共聚物中ＭＭＡ聚合链段与橡胶链段的相对比例（重量比）明显增加。

The copolymerization of methyl methacrylate into natural rubber latex and degraded natural rubber latex was carried out. The seperation of overall copolymerization product was studied and a new method of seperation was found out. It was found that the ratio between PMMA and natural rubber in copolymer was increased with the degradation time increasing.
