The heat stability, thermal decomposition behavior and the effect of light aging on performance of HPVC were studied.
主要研究了高聚合度聚氯乙烯（H PVC）的热稳定性和热分解过程以及光老化对HPVC性能的影响。
The results show that the higher the degree of polymerization is, the better heat stability of HPVC resin is, and the better light aging resistance of HPVC is.
结果表明，聚合度越高，树脂的热稳定性越好，HPVC的耐光老化性能明显优于普通聚合度聚氯乙烯(pvc)。
The artificially aging was done by simulating three main natural aging factors: light, heat and hydrolysis.
人工老化包括光老化、 热老化和水解老化。
