摘　　要：以丙烯酸类单体和废革屑中提取的胶原蛋白为原料,以过硫酸钾（KPS）为引发剂,选用阴离子和非离子乳化剂进行复配作为乳化剂,通过种子乳液聚合方法合成胶黏剂,采用FTIR、TG等测试技术进行表征,考察单体的配比、加料方式、复配乳化剂用量、反应温度、反应时间等因素对乳液性能和胶膜性能的影响。研究结果发现,最佳反应条件为：采用半连续种子乳液聚合法,软硬单体配比为9∶1、乳化剂用量为2%、反应温度为85℃,反应时间为5-6 h。Adhesives wassynthesized by the semi-continuous seed emulsion polymerization, using acrylic monomer and- collagenextracted from leather waste as raw material, potassium persulfate （KPS） as initiator, anionic and non-ionic emul- sifiers as an emulsifier. The products characterized by FTIR, TG.The effect of monomer ratio, feeding methods,amountof emulsifier, reaction temperatureand time on the properties of emulsion and film. The results showed that： when the mass proportion of soft＇and hard monomer at 9：1, emulsifier at 2%, the reaction temperature at 85 ℃ and the reaction time at 5-6 h, thecomprehensive performance of the emulsion and film are best.
