摘　　要：采用零长毛细管流交仪测量了不同助剂对ＰＶＣ复合物在滚压过程中凝胶度的影响与性能的关系。结果表明，在本实验条件下，随加工温度的升高，体系凝胶度增大，共混体的性能也逐渐改善。对ＰＶＣ／ＡＣＲ—２０１和ＰＶＣ／ＡＳ体系，在加工温度为１８０℃时，凝胶化度为８０％～９５％时（测试温度１６０℃，测试压力１２０ｋｇ），其综合性能最佳。The effects of different additives on the gelation level of PVC compound in therollmilling process were measured and the relationshiPS betWeen the gelation level and the Properties were investigatedby zero-length capilary rheometer. Underthe given experimental condition, the gelation level of the system increased with processing temperature and the properties of the blendsystem also improved. For the PVC/ACR-201 and PVC/AS Systems, when the Processing temperature was 180℃ and the gelation level was 80%～95%,i. e. (Tt=160℃ W=120kg),their overall Properties were optimal.
