摘　　要：乙烯 /苯乙烯假无规共聚物 (ESI)是一类新型的茂金属聚合物 ,通常苯乙烯质量分数可达80 %。随苯乙烯的质量分数增加 ,ESI由半晶态的弹性体材料过渡到非晶态的热塑性塑料。笔者综述了近年来国外茂金属乙烯 -苯乙烯假无规共聚物 (ESI)研究与开发的新进展 ,重点介绍了ESI的物理性能、合成工艺、共混性能、填充性能、膜塑性能及发泡性能 。Ethylene-Styrene Interpolymers (ESIs) are a series of novel metallocene polymers, typically containing up to about 80% styrene. These ESIs encompass materials ranging from semi-crystalline elastomers to amorphous thermoplastics, depending upon the styrene content copolymer in. New research and development advancement of ESI from foreign countries is reviewed. Physical properties, polymerization technology, blending properties, filling properties, film properties and foam properties of ESI are mainly introduced, meanwhile the current application and developing trends of ESI are discussed.
