| 摘 要： | NBR－PPC弹性体偶联剂能促进PPC（聚丙撑碳酸酯）与PVC（聚氯乙烯）之间的相容性，改善共混物的力学性能，并在共混体系中产生轻度交联。偶联剂组成在NBR／PPC比例为70／30，NBR（丁腈橡胶）含腈量为34％，BPO过氧化苯甲酸用量为2．5份时，共混物的综合力学性能最佳，但偶联剂预先硫化时间不宜过长．

| Abstract: | NBR-PPC as coupling agent can promote compatibility of poly(viny chloride) (PVC) with poly(propylene carbonate) (PPC),great1y improves mechamcal properties of PVC/PPC system, causes light crosslinking. Mechanical properties of PVC/PPC blends are generally best when the ratio of NBR/PPC is 70/30, nitrile percent of NBR 34%,BPO amount 2. 5 phr in coupling agent. But pre-vulcanhation of coupling agent had bet-ter take a short time. |
