摘　　要：系统地评述了不同方法改性聚苯乙烯(PS)的机械性能与耐热性,包括(未官能化、官能化)无机填料直接填充或在聚合过程中原位填充改性;(未改性、改性)聚合物直接共混或在聚合过程中原位共混改性;离子交联、互穿聚合物交联网络、共价交联改性;从单体出发采用无规、接枝或嵌段共聚改性;以及同时使用两种方法的耦合改性(如共混-填充、共聚-共混、共聚-填充、离子交联-共混、离子交联-填充)等。在此基础上,对各种改性方法的优缺点进行了比较与讨论。In this article, different methods to modify mechanical properties and heat resistance of polystyrene （PS） have systematically been reviewed. These include filling the PS directly or in situ during its polymerization with inorganic fillers, unfunctionalized or functionalized, blending the PS directly or in situ during its polymerization with polymers, unmodified or modified, cross-linkings （ionic cross-linking, interpenetrating polymer network, covalent cross-linking, etc. ）, random, graft or block copolymerization starting from monomers, two method coupled modifications （e. g., blending-filling, copolymerization-blending, copolymerization-filling, ionic crosslinking-blending, and ionic crosslinking- filling）, etc. Based on the above, the advantages and disadvantages have been compared and discussed of various modification methods.
