摘　　要：采用N,N-4,4双(4-羧酸邻苯二甲酰亚胺基)二苯甲烷(BTI),N,N-4,4双(4-羧酸邻苯二甲酰亚胺基)二苯醚(BEI),N,N-4,4双(4-羧酸邻苯二甲酰亚胺基)二苯砜(BSI)三种不同结构亚胺二元酸中间体,通过熔融缩聚分别合成出新型含亚胺结构的不饱和聚酯树脂。利用DSC、TG等方法研究了不饱和聚酯/玻璃纤维复合材料的热性能和流变性能。结果表明,在不饱和聚酯分子链段中引入亚胺结构,复合材料的热性能得到明显改善,含BEI复合材料的表观分解温度提高了38℃;含BTI复合材料的熔体质量流动速率达到186.286g/10min,提高了76.368g/10min。Unsaturated polyester resin was synthesized from 4, 4＇-diaminediphenyl-methane （BTI）, 4, 4＇- dianminodiphenylrther （BEI） and 4, 4＇-diamlnodiphenylsulfone （BSI） by means of melt condensation. The thermal and theological properties of unsaturated poly（ester-imide）/glass fiber composites were studied by means of DSC and TG. The results showed after the incorporation of imide groups to the molecular chains of the unsaturated polyester, the thermal property of the composite was improved obviously; the apparent decomposition temperature of the composite containing BEI was 38 ℃ higher than that of the composite without imide; the MFI of the composite containing BTI was up to 186.286 g/10 min, being 76.368 g/10min higher.
