| 摘 要： | 采用反应型乳化剂1-丙烯基-2-羟基烷磺酸钠(COPS-Ⅰ)与阴离子乳化剂聚氧乙烯-4-酚基醚硫酸铵(CO-436)复配乳化体系,制备了丙烯酸酯共聚物核壳乳液,主要探讨了不同的制备方法、不同单体(甲基丙烯酸甲酯MMA、苯乙烯St、丙烯酸丁酯BA、丙烯酸AA)的用量、引发剂过硫酸铵(APS)的用量、种子乳液用量以及乳化剂COPS-Ⅰ与CO-436配比等因素对乳液和乳胶膜性能的影响。测试结果表明,当采用半连续种子乳液聚合方法,MMA∶St∶BA∶AA质量比为18∶16∶14∶1,种子乳液的质量为10%,COPS-Ⅰ与CO-436质量比为4∶1,APS的质量为0.5%～0.7%时,得到的丙烯酸酯共聚物乳液和乳胶膜的综合性能较好。

| Abstract: | In this work,the core-shell acrylic copolymer latexes are prepared by using reactive emulsifier COPS-I and anion emulsifier CO-436.The effects such as the feeding method,the mass ratio of monomers(MMA,St,BA,AA),the amount of the initiator APS,and the seed emulsion,and the emulsifiers COPS-I and CO-436 on the properties of acrylic copolymer latexes and films are studied.The results show that the acrylic copolymer latexes and films with better integrative properties are obtained,when the feeding method of she... |
