摘要
采用预乳化半连续种子乳液聚合工艺制备聚丙烯酸酯类乳液,在聚合过程中以环保的脂肪醇聚氧乙烯醚(AEO-9)、脂肪醇聚氧乙烯醚磺基琥珀酸单酯二钠(A-102)、失水山梨醇油酸酯聚氧乙烯醚(Tween 80)替代传统的烷基酚聚氧乙烯醚(APEO)乳化剂,并探讨了不同乳化剂对聚合物乳液粘度、残单量、分子量、稳定性、玻璃化转变温度和粒径形貌的影响规律。结果表明,通过采用绿色乳化剂替代APEO,不仅实现了乳液聚合的生态安全,且乳液综合性能良好。
A polyacrylate emulsion was prepared by pre-emulsified technique,adopting semi-continuous seeded emulsion polymerization methods.Choosing environmental friendly alcohol ethoxylates（AEO-9）,sulfosuccinic acid alkyl polyoxyethylene monoester disodium salt（A-102） and sorbitan monooleate（Tween 80） instead of traditional alkyl phenol ethoxylates（APEO） as surfactants in polymerization.In this article,the effects of these surfactants on viscosity,residual monomer,molecular weight,stability,glass transition temperature with particle diameter of emulsion were explored.The results show that substitutions of APEO by green surfactants realize the ecological security of polymerization.In addition,the emulsion properties are excellent.
