选用二烯丙基二甲基氯化铵(DMDAAC)与丙烯酸丁酯(BA)、甲基丙烯酸甲酯(MMA)通过无皂乳液聚合法制备了聚二烯丙基二甲基氯化铵-丙烯酸丁酯甲基丙烯酸甲酯(PDMDAAC-BA-MMA)乳液,采用单因素实验法分别考察了引发剂用量、反应温度和DMDAAC用量对乳液性能的影响.通过傅里叶红外光谱(FT-IR)、动态激光光散射(DLS)、透射电镜(TEM)等表征手段对PDMDAAC BA MMA进行了表征.FT-IR结果表明单体成功发生了聚合.DLS和TEM结果表明乳胶粒子直径大约在800nm左右,呈典型的核壳结构.将其应用于皮革涂饰工艺中,应用结果表明,与市场产品相比,自制乳液涂饰后革样的抗张强度、吸水率和干湿擦牢度相当,断裂伸长率有大幅度提高.%Polymer diallydimethyl ammonium chloride-butylacrylate-methyl methacrylate (PDMDAACBA-MMA) was prepared by emulsifier-free emulsion copolymerization . In single factor experiment method, the in-fluence of synthetic conditions, such as the dosage of initiator, system temperature and the content of dial-lyldimethyl ammonium chloride on the properties of latex was investigated in details. The latex was character-ized by Fourier transform infrared spectroscopy(FT-IR), dynamic laser scattering(DLS) and transmission elec-tron microscope(TEM). FT-IR indicated that polymerization was happened. DLS and TEM indicated that the average diameter of the polyacrylate latex particles was about 800nm with core-shell structure. Tensile strength, water absorption and dry and wet rub fastness of leather finished by PDMDAAC-BA-MMA was simi-lar to leather finished by market products, elongation at break of leather was improved.
