国产水分散型助分散剂在氯乙烯聚合中的应用

Application of domestic water dispersion type secondary dispersant in polymerization of VCM

通过对国内外各种助分散剂的应用对比,针对PVC生产中存在的问题,在油溶性PVA生产技术基础上,添加VAC共聚单体,研制开发出一种水分散型助分散剂,其各项性能达到国外同类产品水平,现已工业化生产,应用于国内部分PVC厂家。

The application of various secondary dispersants produced at home and abroad were compared.According to the problems existing in PVC production,a new kind of water dispersion type secondary dispersant was developed on the basis of oil-soluble PVA production technology by adding VAC comonomer.The performance indexes of the new secondary dispersant could reach those of the same foreign products.The new secondary dispersant had been commercially produced and applied to some domestic PVC enterprises.
