聚乙烯吡咯烷酮(PVP)是一种水溶性聚合物,其共聚与三元共聚以及离子类型决定了它的广泛用途,包括胶粘剂、增稠或防卷曲添加剂、分散剂、固色剂、成膜剂、稳定剂、浓缩剂和稳定释放剂。全球大约有26%的PVP产量用于制药和化妆品/个人护理用品行业,7.4%用于食品行业,5.5%用于印刷行业,涂料和添加剂行业各占4.9%,另外还有4.8%用于摄影行业。 PVP分为液态和固态两种,最普遍的是粉末、水溶液和有机溶液。其产品类型包括均相PVC、交联PVC以及30多种阳离子、阴离子和非离子共聚、三元聚合PVC。生产PVP的工艺主要有两种。第一种工艺是将乙烯基吡咯烷酮置入有机溶剂中进行溶液聚合,然后进行蒸汽分离,制成PVP水
Polyvinylpyrrolidone (PVP) is a water-soluble polymer whose copolymerization and terpolymerization as well as its ionic species determine its wide range of uses including adhesives, thickening or anti-curling additives, dispersants, fixing agents, film formers , Stabilizers, concentrates and stabilizers. Approximately 26% of the world’s PVP production is used in the pharmaceutical and cosmetic / personal care industries, 7.4% in the food industry, 5.5% in the printing industry, 4.9% each in the coating and additives industry, and 4.8% in photography industry. PVP is divided into liquid and solid two kinds, the most common is powder, aqueous solution and organic solution. Its product categories include homogeneous PVC, cross-linked PVC and more than 30 cationic, anionic and non-ionic copolymerization, terpolymeric PVC. There are two main processes for producing PVP. The first process is the vinyl pyrrolidone into organic solvent for solution polymerization, and then steam separation, made of PVP water
