摘　　要：以丙烯酸甲酯、苯乙烯和阳离子单体为主要原料,采用无皂聚合法制备了阳离子聚丙烯酸酯乳液(CPEE),优化的制备工艺为:阳离子单体用量为总单体量的5%,引发剂用量为总单体量的1%。CPEE、阳离子聚酰胺多胺环氧氯丙烷(PAE)和阳离子淀粉(CS)作为施胶增效剂,用于阳离子石油树脂胶在草浆中的施胶,能够实现中性施胶并取得较好的施胶效果。CPEE和PAE配合使用可明显提高纸页的施胶度和裂断长,效果优于普通的助留剂。The cationic polyacrylic ester emulsion (CPEE) was produced from methyl acrylate, styrene, cationic monomer and other chemicals by means of soap-free polymerization. The optimum condition of preparation was as follows : cationic monomer and initiator were 5% and 1% in the total monomer respectively. CPEE, polyaminoamide-epichlorohydrin (PAE) and cationic starch (CS) were used as potentiating agent in the sizing of straw stock. With the help of the above polymers, cationic petroleum resin sizing agent could be used at neutral conditions to produce good sizing effect. Experimental result indicated that CPEE and PAE could apparently improve sizing degree and break length of paper sheet when used together properly. The above two polymers had better potentiation effect on sizing than ordinary retention aids commonly used in papermaking.
