摘　　要：通过熔融共混制备了聚苯硫醚/无苯基聚甲基乙烯基硅氧烷(PPS/NPMVS)共混物及聚苯硫醚/单苯基聚甲基乙烯基硅氧烷(PPS/SPMVS)共混物,并对该共混物体系的微观形貌及力学性能进行了分析表征。结果表明,弹性体在共混物中均匀分散,弹性体的加入对PPS基体起到明显的增韧效果;当弹性体的含量为3%(质量分数,下同)时,2种共混材料的增韧性能最佳,PPS/NPMVS共混材料的断裂伸长率相对于PPS基体提高了3.9倍,PPS/SPMVS共混材料的断裂伸长率相对于PPS基体提高了2.4倍;当NPMVS含量为10%时,PPS/NPMVS共混材料的冲击强度相对于PPS基体提高了1.8倍,当SPMVS含量为3%时,PPS/SPMVS共混材料的冲击强度相对于PPS基体提高了1.4倍。A series of blends based on poly(phenylene sulfide)(PPS) and poly(methyl-vinyl siloxane)(PMVS) were prepared by melt mixing process.The mechanical properties and the fracture morphology of the blends were investigated.It showed that the elastomers were well dispersed in PPS matrix.The toughening effect of the elastomers was obvious.When the mass fraction of the elastomers was 3%,the elongation at break of PPS/NPMVS and PPS/SPMVS blends were 3.9 and 2.4 times higher than that of neat PPS,respectively.The impact strength of PPS/NPMVS(NPMVS 3 mass%) and PPS/SPMVS(SPMVS 10 mass%) blends were 1.8 and 1.4 times higher than those of neat PPS,respectively.
