Has developed into non-ionic, cationic, anion 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 have been widely used.PVP is divided into four stages according to its average molecular weight size, which is usually expressed by the K value, and different K values represent the corresponding average molecular\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":[],"attr":[111],"class_list":["post-1712","post","type-post","status-publish","format-standard","hentry","category-problems"],"_links":{"self":[{"href":"https:\/\/www.yearnintl.com\/ko\/wp-json\/wp\/v2\/posts\/1712","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=1712"}],"version-history":[{"count":3,"href":"https:\/\/www.yearnintl.com\/ko\/wp-json\/wp\/v2\/posts\/1712\/revisions"}],"predecessor-version":[{"id":1716,"href":"https:\/\/www.yearnintl.com\/ko\/wp-json\/wp\/v2\/posts\/1712\/revisions\/1716"}],"wp:attachment":[{"href":"https:\/\/www.yearnintl.com\/ko\/wp-json\/wp\/v2\/media?parent=1712"}],"wp:term":[{"taxonomy":"category","embeddable":true,"href":"https:\/\/www.yearnintl.com\/ko\/wp-json\/wp\/v2\/categories?post=1712"},{"taxonomy":"post_tag","embeddable":true,"href":"https:\/\/www.yearnintl.com\/ko\/wp-json\/wp\/v2\/tags?post=1712"},{"taxonomy":"attr","embeddable":true,"href":"https:\/\/www.yearnintl.com\/ko\/wp-json\/wp\/v2\/attr?post=1712"}],"curies":[{"name":"wp","href":"https:\/\/api.w.org\/{rel}","templated":true}]}}
