摘要： 丙烯酸丁酯-苯乙烯-丙烯腈共聚物(ASA)是两相结构,聚丙烯酸丁酯(PnBA)以弹性体粒子的形式分散在刚性的苯乙烯一丙烯睛共聚物((SAN)基体中.PnBA链不含双键,耐侯性优越,可用作户外结构材料.

关键词: ASA, 乳液聚合, 粒子, 力学性能

Abstract: Poly(n-butyl acrylate)/styrene/acrylonitrile copolymer(ASA) was synthesized,and its structure-property relationship was studied.It was found that the rubber particle size can be controlled by using the seed emulsion polymerization technique.The impact strength of the ASA depends on its composition and rubber particle size.The optimum particle size is 0.135μm,and the optimum composition of the matrix is 28/72(AN/St).

Key words: poly(n-butyl acrglate)/styrene/acrylonitrile, emulsion polymerization, particle, mechanical property
