摘要:
The present disclosure provides a process for the chlorination of polyvinyl chloride. PVC obtained during the suspension polymerization reaction is directly used for chlorination without filtration, drying and re-slurrying. The present process is carried out in the absence of additional chemicals/reagents; also reheating during the chlorination reaction is not required. CPVC manufactured using the process of the present disclosure has whiteness index greater than 85, yellowness index lower than 4 and thermal stability in the range of 300 to 550 seconds at 210 °C.
摘要(中):
本公开提供了氯化聚氯乙烯的方法。 在悬浮聚合反应中获得的PVC直接用于氯化而不进行过滤,干燥和再浆化。 本方法在没有其他化学品/试剂的情况下进行; 在氯化反应期间也不需要再加热。 使用本公开的方法制造的CPVC在210℃下的白度指数大于85,黄度指数低于4,热稳定性在300至550秒的范围内。
