改性B72比纯b 72有更好的耐光老化性能。
Compared with B72, the modified one has better anti-photodegradation.
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 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.
