PVP POvidone introduction Polyvinylpyrrolidone (PVP) is a water-soluble polymer formed by linear polymerization of N-vinylpyrrolidone (NVP). Its molecular structure formula is shown in Figure 1.1. In 1938, German chemist Reppe first used acetylene as raw material to synthesize PVP. So far, PVP has developed into non-ionic, cationic, anionic 3 categories, industrial grade, pharmaceutical grade, food grade 3 specifications, relative molecular mass from thousands to more than one million homopolymer, copolymer and crosslinked polymer series products, and with its excellent unique properties are widely used. PVP not only has the general properties of water- soluble polymers, such as colloidal protection, film formation, bonding, hygroscopicity, thickening, condensation and complexation ability with some compounds, but also has been paid attention to by people for its excellent solubility and physiological compatibility. In the synthetic polymer products, such as PVP is soluble in water, but also soluble in most organic solvents, extremely low toxicity, physiological\u2026<\/p>","protected":false},"author":1,"featured_media":0,"comment_status":"open","ping_status":"closed","sticky":false,"template":"","format":"standard","meta":{"footnotes":""},"categories":[3],"tags":[79],"attr":[],"class_list":["post-911","post","type-post","status-publish","format-standard","hentry","category-problems","tag-polyvinylpyrrolidone"],"_links":{"self":[{"href":"https:\/\/www.yearnintl.com\/ko\/wp-json\/wp\/v2\/posts\/911","targetHints":{"allow":["GET"]}}],"collection":[{"href":"https:\/\/www.yearnintl.com\/ko\/wp-json\/wp\/v2\/posts"}],"about":[{"href":"https:\/\/www.yearnintl.com\/ko\/wp-json\/wp\/v2\/types\/post"}],"author":[{"embeddable":true,"href":"https:\/\/www.yearnintl.com\/ko\/wp-json\/wp\/v2\/users\/1"}],"replies":[{"embeddable":true,"href":"https:\/\/www.yearnintl.com\/ko\/wp-json\/wp\/v2\/comments?post=911"}],"version-history":[{"count":5,"href":"https:\/\/www.yearnintl.com\/ko\/wp-json\/wp\/v2\/posts\/911\/revisions"}],"predecessor-version":[{"id":1570,"href":"https:\/\/www.yearnintl.com\/ko\/wp-json\/wp\/v2\/posts\/911\/revisions\/1570"}],"wp:attachment":[{"href":"https:\/\/www.yearnintl.com\/ko\/wp-json\/wp\/v2\/media?parent=911"}],"wp:term":[{"taxonomy":"category","embeddable":true,"href":"https:\/\/www.yearnintl.com\/ko\/wp-json\/wp\/v2\/categories?post=911"},{"taxonomy":"post_tag","embeddable":true,"href":"https:\/\/www.yearnintl.com\/ko\/wp-json\/wp\/v2\/tags?post=911"},{"taxonomy":"attr","embeddable":true,"href":"https:\/\/www.yearnintl.com\/ko\/wp-json\/wp\/v2\/attr?post=911"}],"curies":[{"name":"wp","href":"https:\/\/api.w.org\/{rel}","templated":true}]}}
