通过半连续种子乳液聚合工艺，成功合成了软包装用耐水丙烯酸酯胶黏剂乳液，并考察了乳化剂、引发剂、种子乳液以及交联单体对乳液性能的影响，测定了乳液平均粒径随反应时间的变化情况。结果表明，各种功能单体、反应性乳化剂均参与了共聚，并且相应基团的红外光谱（FT-IR）特征吸收峰比较明显；当反应性乳化剂（COPS-1/AMPS=1∶1）用量(质量分数)为2.0%~2.5%，引发剂(APS)用量为0.45%，种子乳液用量为8%~10%，交联单体1,6-己二醇二丙烯酸酯（HDDA）用量为8%左右时，丙烯酸酯胶黏剂乳液综合性能最佳。

Waterproof acrylic adhesive emulsion for soft packaging was synthesized by the method of multi-step seeded emulsion polymerization. Effects of the emulsifier, initiator, seed emulsion, and cross-linking monomers on adhesive properties were investigated respectively. Average particle size of emulsion was determined with the reaction time. The results showed that the functional monomers and emulsifier all participate in the copolymerization reactions; the absorption peaks of corresponding groups were obviously observed in infrared spectroscopy (FT-IR); acrylic emulsion adhesive has the best combination property when the dosage of reaction type emulsifier（COPS-1/AMPS=1∶1） is 2.0%~2.5wt%, the dosage of initiator(APS) is 0.45wt% , the dosage of seed emulsion is 8%~10wt%, the dosage of HDDA was 8wt%.
