PBA－g－AS共聚物的合成

SYNTHESIS OF THE PBA-G-AS COPOLYMER

本文以交联ＰＢＡ为主链，ｇｒ和ＡＮ为接技单体，通过乳液接枝共聚会成了ＰＢＡ－ｇ－ＡＳ井聚物．研究了乳化剂加入量、引发剂种类及用量、单体加入方式及单体浓度、反应时间以及ＰＢＡ胶乳性质等对接枝率、转化率及粒子形态的影响，同时也研究了ＴＤＭ用量对接枝链分子量及接枝率的影响．

The title copolymer is synthedzed by emulSion grafting copolytherization,using a cross-linkedPBA as ban-chain and the mixture of ST and AN as grafting monomers.It has been found that manyfactors,such as, the concentration of emulsifying agent, the type and concentrstion of initiator,themanneds of feeding,the concentration of monomer,the reaCtion time and the properties Of PBA latex,have influenced on the degree of gtaft, convedon of monomers and Particle morphology. In addition,the effect of the concentration of TDM on the degree of fraft and molecular weight of grafting-chainhas been studied,too
