摘　　要：用自由基溶液聚合法合成了甲基丙烯酰乙基三甲基氯化铵(DMC)-丙烯酸乙酯(EA)-甲基丙烯酸缩水甘油醚(GMA)和DMC-EA-GMA-甲基丙烯酸甲酯(MMA)共聚物,并以此为成膜树脂制备了相应的防污涂料。测试结果表明:随着成膜树脂中DMC用量的增加,涂膜的剪切强度下降,Cu2+渗出率增加;随MMA用量的增加,涂膜的抗拉强度增加,Cu2+渗出率增加。MMA用量为树脂质量10%时,15℃以上的Cu2+渗出率明显高于10℃时的Cu2+渗出率,这对防污剂氧化亚铜的温控释放是十分有利的。Methacryloxy ethyl trimethyl ammonium chloride（ DMC）-ethyl acrylate（ EA）-glydyl methacrylate（ GMA） and DMCEA-GMA-methyl methacrylate（ MMA） copolymers were synthesized by free-radical solution polymerization,and the antifouling coatings were prepared. The measurement results show that shear strength of the coatings decreases and Cu2 ＋release rate increased with increasing DMC amount,and tensile strength and Cu2 ＋released rate of the coatings increased with increasing MMA amount. When the content of MMA was 10% of resin,Cu2 ＋release rate at 15 ℃ was obviously higher than that at 10 ℃,which is very favorable for the temperature-controlled release of cuprous oxide.
