丙烯酸改性氯醚树脂乳液的合成研究
Keywords: 氯醚树脂,丙烯酸酯,接枝共聚,乳液
Abstract:
？采用溶液聚合法，以丙烯酸（aa）、丙烯酸丁酯（ba）和甲基丙烯酸甲酯（mma）为混合单体，与氯醚树脂（vc-ibve）进行接枝共聚；用中和剂三乙胺（tea）与接枝反应产物中和成盐，得到水性丙烯酸改性氯醚树脂乳液。讨论了引发剂浓度对该体系接枝率的影响，重点研究了丙烯酸类单体用量以及混合单体中丙烯酸和丙烯酸丁酯的含量对改性乳液性能的影响。结果表明：丙烯酸类单体用量为50%，混合单体中丙烯酸和丙烯酸丁酯的含量分别为9%～11%和40%时，制得的改性乳液具有良好的稳定性、耐盐水性和优异的附着力。并用红外光谱（ft-ir）和透射电子显微镜表征（tem）了此改性乳液。
