[Chemical name]: Cross-linked polyvinyl pyrrolidone (pvpp) [alias]: insoluble POvidone, crosslinked pvp, polyethylene polypyrrolidone Molecular formula (CH,NO)n This product is a water-insoluble homopolymer synthesized from n-ethylene-2-pyrrolidone. The molecular formula is (C6H9NO)n, where n represents the average number of 1-vinyl-2-pyrrolidone chains. According to anhydrous matter, nitrogen (N) should be 11.0%~12.8%. Source and preparation N-vinyl-2-pyrrolidone is polymerized and crosslinked in the presence of basic catalyst or N1-divinylimidazole to produce a crude homopolymer. Then water, 5% acetic acid and 5% ethanol are returned to the extract <=50mg\/kg to obtain a pure crosslinked homopolymer. The whole synthesis time is about 3 hours. character This product is white or near white, with hygroscopic easy to flow powder, odorless or slightly odorless, insoluble in water, alkali, acid and common organic solvents, so the molecular weight range can not be measured. This product has a high capillary\/water capacity, large specific surface area, strong hydration ability(HK=5.6), high and rapid\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":[95],"attr":[],"class_list":["post-879","post","type-post","status-publish","format-standard","hentry","category-problems","tag-crosslinked-polyvinylpyrrolidone"],"_links":{"self":[{"href":"https:\/\/www.yearnintl.com\/ko\/wp-json\/wp\/v2\/posts\/879","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=879"}],"version-history":[{"count":5,"href":"https:\/\/www.yearnintl.com\/ko\/wp-json\/wp\/v2\/posts\/879\/revisions"}],"predecessor-version":[{"id":1563,"href":"https:\/\/www.yearnintl.com\/ko\/wp-json\/wp\/v2\/posts\/879\/revisions\/1563"}],"wp:attachment":[{"href":"https:\/\/www.yearnintl.com\/ko\/wp-json\/wp\/v2\/media?parent=879"}],"wp:term":[{"taxonomy":"category","embeddable":true,"href":"https:\/\/www.yearnintl.com\/ko\/wp-json\/wp\/v2\/categories?post=879"},{"taxonomy":"post_tag","embeddable":true,"href":"https:\/\/www.yearnintl.com\/ko\/wp-json\/wp\/v2\/tags?post=879"},{"taxonomy":"attr","embeddable":true,"href":"https:\/\/www.yearnintl.com\/ko\/wp-json\/wp\/v2\/attr?post=879"}],"curies":[{"name":"wp","href":"https:\/\/api.w.org\/{rel}","templated":true}]}}
