乳液聚合以其反应速度快、反应条件温和等优点而得到广泛的应用,但乳化剂的存在给聚合物的性能、乳液的稳定带来了许多不良影响。外加对反应有促进作用的甲醇、丙酮来实现无皂乳液聚合,由于引入有机试剂而带来了污染;离子型共聚单体乳化剂参与疏水单体的无皂乳液聚合,使乳液中不存在游离的乳化剂,可得到粒径(及其分布)小而洁净的乳胶粒。 Emulsion polymerization is widely used because of its fast reaction rate, mild reaction conditions and the like. However, the presence of an emulsifier has many adverse effects on the properties of the polymer and the stability of the emulsion. Plus methanol and acetone to promote the reaction to achieve soap-free emulsion polymerization, which brings about pollution due to the introduction of organic reagents. The ionic comonomer emulsifier participates in the soap-free emulsion polymerization of the hydrophobic monomer to make the emulsion have no free Of the emulsifier to obtain a particle size (and its distribution) small and clean latex particles.
