一种抗冲改性树脂的合成

SYNTHESIS OF A KIND OF RESIN USED AS IMPACT MODIFIER

以交联丙烯酸丁酯胶乳为基础胶乳 (PBA) ,用苯乙烯 (St)、丙烯腈 (AN)为接枝单体接枝聚丙烯酸丁酯胶乳粒子上 ,形成核壳结构 ,该树脂是优异的树脂抗冲改性剂。得出了补加乳化剂、引发剂、单体浓度、苯乙烯 /丙烯腈配比、链转移剂用量对丙烯酸丁酯接枝聚合的影响规律。制得了抗冲改性树脂。

Synthesis method for the resin is:crosslinked polybutyl acrylate latex is used as base latex,styrene(St) and acrylonitrile(AN) are grafted into polybutyl acrylate latex particle,and turn into core-shell polymer.The influences of additive emulsifier,initiator,monomer concentration,the ratio of St to AN,and chain transfer agent on graft polymerization are studied.A kind of resin used as impact modifier is obtained.
