摘　　要：:探讨了丙烯酸 -苯乙烯 -甲基丙烯酸甲酯水溶性三元共聚物的合成条件 ,研究了这种水溶性三元共聚物的性质及其在造纸过程中的可能应用。研究发现 ,在适当的条件下 ,丙烯酸 -苯乙烯 -甲基丙烯酸甲酯可以按一定的摩尔比发生共聚合形成能溶于水的共聚物。这种水溶性的共聚物在高温下 (大于 80℃ )发生固化后而形成具有抗水性的膜 ,因而适合于造纸工业作施胶剂 ,但是 ,由于其分子量不高留着率低 ,要与松香配合使用 ,使松香施胶剂发挥更大的效果 ,实验证明 。The synthesis condition of water-soluble co-polymer of acrylic acid-styrene-methylmethyl acrylate was investigated.The application in paper making for sizing was studied.It was found that co-polymerization of three monomer mentioned above can occur in a suitable condition.This water-soluble co-polymer can take place solidification at high temperature(higher then80℃)and form a water-insoluble film.Therefore,that is suitable for sizing in paper making.If it is used with resin together,the sizing effect can be double enhanced .
