摘　　要：苯乙烯-马来酸酐共聚物(SMA)是一类特种热塑性材料,具有很好的耐热性和可加工性,且能与多种树脂共混。用热分析方法对其无规性、热稳定性、加工性能和热老化性能进行表征,以促使SMA树脂掺混到多个体系,开发出系列高性能工程塑料合金。Styrene - maleic anhydride copolymer (SMA) is one kind of special thermoplastic material with superior heat - resistance, and is capable to blend with many kinds of resins. The random - ness, thermal stability, processability and thermal aging of the SMA was characterized with thermal analysis methods, aimed at developing novel engineering plastic alloys with high performance by blending SMA with other resin systems.
