摘　　要：物理共混法、自由基共聚合法和阴离子聚合法是制备透明高抗冲聚苯乙烯(THIPS)树脂的主要方法。而自由基共聚合法又可分为乳液法、溶液法、本体-悬浮法和连续本体法等。综述了国内外在THIPS树脂领域中的研究进展及国内在THIPS中试及工业化进程中取得的成果,并讨论了增韧剂种类、聚合方法、相对分子质量和残留单体量等因素对THIPS树脂的透光率、形态结构以及力学性能的影响。Physical blending method, free radical copolymerization method and anionic polymerization method are the main approaches for preparing transparent high impact polystyrene（THIPS） resin. Free radical copolymerization method can be further divided into emulsion, solution, bulk-suspension and continuous bulk polymerization method and so on. The research progress in THIPS resin at home and abroad was summarized with the emphasis on domestic achievements in the pilot plant and industrialization process of THIPS. The influence of toughener type, polymerization method, relative molecular mass and residual monomer amount, etc. on the transparency, morphological structure and mechanical properties of THIPS were discussed.
