PVP has unique three-dimensional structure and physical and chemical properties, and is widely used in medicine, cosmetics, food and industry. structureThe molecular structure of PVP is formed by polymerization of vinylpyrrolidone monomer (n-vinylpyrrolidone). The vinylpyrrolidone molecule consists of a pyrrolidone ring and a vinyl group. In the polymerization process, the vinyl reacts with oxygen atoms on the pyrrolidone ring to form a polymerization chain. The molecular weight of PVP can be controlled by adjusting the amount of vinylpyrrolidone monomer and the polymerization conditions. The three-dimensional structure of PVP is mainly determined by the conformation of the polymerization chain. Due to the limitation of the bond length and bond Angle between vinyl and the oxygen atom on the pyrrolidone ring, the PVP polymerized chain presents a curved conformation. This conformation makes PVP have high solubility and fluidity, can\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":[94],"attr":[],"class_list":["post-874","post","type-post","status-publish","format-standard","hentry","category-problems","tag-pvp"],"_links":{"self":[{"href":"https:\/\/www.yearnintl.com\/ko\/wp-json\/wp\/v2\/posts\/874","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=874"}],"version-history":[{"count":5,"href":"https:\/\/www.yearnintl.com\/ko\/wp-json\/wp\/v2\/posts\/874\/revisions"}],"predecessor-version":[{"id":1562,"href":"https:\/\/www.yearnintl.com\/ko\/wp-json\/wp\/v2\/posts\/874\/revisions\/1562"}],"wp:attachment":[{"href":"https:\/\/www.yearnintl.com\/ko\/wp-json\/wp\/v2\/media?parent=874"}],"wp:term":[{"taxonomy":"category","embeddable":true,"href":"https:\/\/www.yearnintl.com\/ko\/wp-json\/wp\/v2\/categories?post=874"},{"taxonomy":"post_tag","embeddable":true,"href":"https:\/\/www.yearnintl.com\/ko\/wp-json\/wp\/v2\/tags?post=874"},{"taxonomy":"attr","embeddable":true,"href":"https:\/\/www.yearnintl.com\/ko\/wp-json\/wp\/v2\/attr?post=874"}],"curies":[{"name":"wp","href":"https:\/\/api.w.org\/{rel}","templated":true}]}}
