摘要
以过硫酸铵(APS)、N,N,N′,N′-四甲基乙二胺(TMEDA)为氧化还原引发剂,对功能性单体丙烯酸(AA)、丙烯酰胺(AM)、N-羟甲基丙烯酰胺(NMA)与甲基丙烯酸甲酯(MMA)、丙烯酸丁酯(BA)、丙烯腈(AN)进行改进的微乳液聚合方法的共聚,获得了固含量高达44.0%、总乳化剂质量分数小于2.0%的平均粒径小于50nm的微胶乳。该微乳液较之常规乳液有粒径小且分布均匀及更优的应用性能。
The microemulsion copolymerizations of acrylic acid (AA), acrylamide (AM), N-methylol acrylamide (NMA), methylmethacrylate (MMA), butyl acrylate (BA) and acrylonitrile (AN) initiated by the redox initiator ammonium persulfate (APS) and N,N,N′,N′-tetramethylethylenediamine (TMEDA) by a new modified microemulsion procedure were investigated. With this process high solids-content ((44.0%)), low surfactants-content ((2.0%)) and small (<50 nm) particle diameters copolymer latexes were attained. In comparison with the conventional emulsion polymerization product, our microemulsion polymerization product has much smaller particle diameter, much narrower distribution, and more excellent other application properties.
