摘　　要：综述了国内外苯乙烯类嵌段共聚物黏弹行为研究进展。着重从苯乙烯类嵌段共聚物溶液和熔体的黏弹行为两方面介绍苯乙烯类嵌段共聚物所表现出的特殊流变特性,以及流变特性与形态结构之间的关联。并基于已有的研究现状提出了苯乙烯类嵌段共聚物黏弹行为研究的前沿与重点。The research progress on the viscoelastic behaviors of styrenic block copolymers at home and abroad is reviewed.The specific rheological characteristics of the styrenic block copolymers and the relationship between the rheological characteristics and morphology structure from two aspects namely viscoelastic behaviors of styrenic block copolymer solutions and melts are emphatically introduced.Based on the existing research status,the research fronts and emphases on viscoelastic behaviors of styrenic block copolymers are proposed.
