| 摘 要： | 将丙烯腈(AN)、苯乙烯(St)在氯化聚乙烯(CPE)存在下进行悬浮接枝共聚,获得了ACS树脂.研究了不同用量ACS树脂对PVC流变行为、力学性能、热性能的影响,用SEM观察其拉伸断面.结果表明,ACS树脂的加入改善了PVC的流动性,其效果比抗冲型ACR好.当ACS加入量为25%时,抗冲强度可提高2～3倍,而抗拉强度变化不大,同时热性能也有所提高.

| Abstract: | The graft terpolymer ACS resin formed from monomer acrylonitrile (AN) and styrene (St) in the presence of CPE was synthesized by suspension polymerization. The effect on rheological behavior, mechanical properties and thermal properties of different content of ACS resin in modifying polyvinyl chloride (PVC) was studied. The tensile fracture surfaces were observed with scanning electron microscope (SEM). The results show that PVC rheological property is enhanced with the feeding of ACS, which is better than impact aid ACR. When the feeding content is 25%, the impact strength of blends increased two to three times and the tensile strength of blends decreased slightly. The thermal properties are also enhanced. |
