Coupling agent promotes the compatibility of poly(vinyl chloride)(PVC) with poly(propylene carbonate)(PPC),greatly improves mechanical properties of PVC/PPC system,causes light cross-linking which is about 10 weight percent of these blends.Mechanical properties of PVC/PPC blends are generally best when the ratio of NBR/PPC is 70/30,nitrile content of NBR 34% and BPO dosage 2.5 parts in coupling agent.And a short pre-vulcanization time for coupling agent is adequate.
