| 摘 要： | 采用凝胶渗透色谱仪（ＧＰＣ），差示扫描热量仪（ＤＳＣ）研究了ＰＶＣＳ—２５００树脂的分子量及其分布、玻璃化转化温度（Ｔｇ），并和ＰＶＣＳ—１０００、Ｓ－１７００树脂进行了比较。并对配合、加工和在１０５℃级电缆中的应用进行了研究。试验结果表明：和低聚合度ＰＶＣ树脂相比，ＰＶＣＳ—２５００树脂的分子量增大、分布变宽、Ｔｇ升高，导致材料的加工温度升高，力学性能提高。可制造优级的耐热电缆料。

| Abstract: | The molecular weight as well as its distribution. and glass transition temperatUre (Tg) of PVC S-2500 were determined with the GPC and the DSC analytical instrument. Its compeison with PVC S-1000 and S-1700 Resins was made. Also, PVC S-2500 used for comPOunding, Processing and making 105℃ grade cable was observed. Compered with PVC resins of lower DP, PVC S-2500 resin was of a higher processing temperature and best mechanical properties due to its higher Mw and higher Tg, and so a good cable compound with higher temperature resistance was developed. |
