丙烯酸甲酯与聚醋酸乙烯酯的核/壳乳液聚合反应

Core-Shell Emulsion Polymerization of Methyl Acrylate on Polymethyl Aacetate

本文研究了丙烯酸甲酯在聚醋酸乙烯酯种子胶粒上的核/壳复合高分子乳液聚合反应。讨论了接枝聚合反应中引发剂的浓度、单体与聚合物的比例、乳化剂用量等工艺参数对该类接枝聚合反应的影响,提出了核/壳乳液聚合反应的一些反应规律。

The core-shell emulsion grafting reaction of methyl acrylate on polyethyl acetate was investigated as a function of (a) in this paper, initiator concentration used in the secondary polymerization, (b), monomer to polymer ratio and (c). emulsifier concentration. The amount of graft polymer was found to decrease with increasing monomer to polymer ratio and degree of conversion. The amount of grafting increassed with in- creasing surface area of the seed latex.
