| 摘 要： | 采用高温连续溶液聚合方法,以甲苯为溶剂,十二烷基硫醇(TDDM)为相对分子质量调节剂,分别以四官能团引发剂和单官能团引发剂过氧化二叔丁基引发合成了苯乙烯-丙烯腈二元共聚物T-SAN和M-SAN,并将其与含胶量为60%的ABS粉料共混制备了不同含胶量的丙烯腈-丁二烯-苯乙烯三元共聚物T-ABS和M-ABS。比较了两种SAN树脂的性能及其对ABS树脂性能的影响。结果表明:相同浓度的四官能团引发剂和单官能团引发剂合成的T-SAN和M-SAN具有相近的相对分子质量及分布,但T-SAN具有更好的流动性和耐热性;T-ABS树脂的冲击强度较M-ABS树脂提高了17%左右,拉伸强度几乎完全相同;橡胶粒子在T-SAN中分散更均匀,粒径更均一,断裂发白区橡胶粒子形变更明显。

| Abstract: | T-SAN and M-SAN resins were synthesized with tetra-and mono-functional initiators via high temperature continuous solution polymerization in toluene,respectively.With nearly the same molecular weight and molecular weight distribution,T-SAN possessed better thermal resistance and melt flow behavior.The two SANs were blended with a same ABS resin forming T-ABS and M-ABS resins.The T-ABS possessed the same tensile strength as M-ABS,but 17 % higher impact strength than M-ABS.The rubber particles in T-SAN were f... |
