| 摘 要： | 观察了聚丙烯(PP)/聚苯乙烯(PS)／(苯乙烯-乙烯/丙烯二嵌段共聚物)(SEP)合金的形态，测定了SEP、SEP/改性蒙脱土复合材料对PP／PS合金的力学性能的影响。结果表明：SEP在EPP／PS合金中作为增容剂，减小了分散相的平均粒子尺寸，大大改变了合金的形态，增强了两相间的粘合力，提高了合金的力学性能，并对PP/PS(20／80)合金的增容作用较为显著。结果还表明：SEP／改性蒙脱土复合材料对PP／PS(20／80)合金具有增韧增强的效果。

| Abstract: | Morphology of PP/PS/(styrene ethylene/propylene diblock copolymer)(SEP)was observed. Effects of SEP and SEP/MMT on mechanical properties of PP/PS alloys were investigated.The results showed that SEP diblock copolymer acted as a compatibilizer in PP/PS alloys; reduced the average particle size of disperse phase and changed their phase morphologies significantly; enchanced the adhesion between the two phases and increased the mechanical properties of the alloys.SEP had obvious compatibilization effects on PP/PS alloys with the ratio of 20/80 .It was also noted that SEP/MMT had toughening and reinforcing effects on PP/PS. |
