摘　　要：以少量环氧类低聚体作增容剂 ,考察了其对聚碳酸酯 /半芳族热致液晶聚合物 (PC/TLCPA1 )体系的增容改性作用。DSC及SEM测试结果表明 ,少量增容剂的加入明显改善了原位复合体系的相容性。力学性能测定结果表明 ,当增容剂加入到含有 2 0 %TLCPA1的复合体系后 。A small amount of epoxy oligomer as compatibilizing agent is used to improve compatibility of in situ composites of polycarbonate(PC)/Thermotropic Liquid Crystalline Polymer(TLCP). The results of DSC and SEM show that the compatibility of in situ composites is improved markedly by adding a small amount of compatibilizing agent. Tensile and bending strength of the composite containing 20% TLCP increases obviously in contrast to the results of incompatibilzing composites.
