摘　　要：选择合适的共聚单体通过乳液聚合制备了聚丙烯酸酯乳液作为涂料的基体。通过竞聚率得出其在理论上的反应的可行性,通过红外、核磁证明合成了对应的目标产物,同时对聚合物的分子量、成膜性、可剥离性、耐化学性进行测试,以说明合成制备所得为目标产物以及制备的聚合物基材较优良的性能。结果表明,乳液成膜膜体的最大的拉伸强度为10.2MPa,断裂伸长率最大可达700%以上。可以很好地从不同基材上剥离,符合制备可剥离涂料的要求。The polyacrylate emulsion was prepared by emulsion polymerization as the substrate of the coating.The feasibility of reaction in theory was obtained by reactivity ratio.IR and NMR proved that the corresponding target product was synthesized,at the same time the molecular weight,film forming,stripping and chemical resistance of polymer were tested,and illustrateed the synthesis of target product and the properties of polymer substrate was excellent.The maximum tensile strength of emulsion forming film was 10.2MPa,the maximum elongation can reach more than 700%.The film can be well stripped from different substrates,in accordance with the preparation requirement of paint can be stripped.
