聚氯乙烯生产聚合后期提高转化率的探索

Discovery on conversion improving in later period of polymerization in PVC production

对聚氯乙烯生产中聚合后期提高聚合温度和单体转化率的方法进行了探索。结果表明,利用该方法能使转化率提高百分之五左右,产品的质量指标达到优级品,但是产品的力学性能受到一定影响。

The process of polymerization temperature and monomer conversion in later period of polymerization in PVC production was discovered. The conversion was increased by 5% with top standard. But the mechanics property was influenced.
