| 摘 要： | PVC中共轭双键产生的有色基团是导致其白度差的重要原因，基于此类PVC与氯乙烯单体共聚合的设计，可有效消除不饱和PVC中的双键；同时，聚合机理分析，经二次聚合改性后PVC中形成的交联、网状结构可提升冀综合性能。 |

| Abstract: | The conjugated double bond begot in PVC results in the whiteness of a sort.In the article,the double bond is to be eliminated effectively on the basis of PVC and VCM copolymerization design.And the polymerization mechanism is analyzed and studied,which demonstrates that the comprehensive performance is able to be gotten further promotion due to the structure of cross-linking and reticulation after modification of second copolymerization in situ. |
