Product Description:

Vinylpyrrolidone-Copolymer (NVP) yog ib qho organic compound uas muaj ib tug 5-membered lactam txuas mus rau ib pawg vinyl. Nws yog cov kua tsis muaj xim txawm tias cov qauv coj mus muag tuaj yeem tshwm daj. Nws yog tsim industrially los ntawm vinylation ntawm 2-pyrrolidone, piv txwv li lub hauv paus-catalyzed cov tshuaj tiv thaiv nrog acetylene.

Lub cev muaj zog:

Nws yog xim tsis muaj xim rau cov kua daj daj ntawm chav tsev kub, yooj yim soluble hauv dej, formaldehyde thiab ntau lwm cov kuab tshuaj organic, thiab crystallizes qis dua 13 degree. N-vinylpyrrolidone yog tshuaj nquag thiab yooj yim hydrolyzed thiab polymerized.

Daim ntawv thov:

Vinylpyrrolidone-Copolymer yog dav siv hauv cov nplaum, textiles, UV txheej, tshuaj thiab lwm yam lag luam. Nws kuj yog siv los tsim homopolymers thiab copolymer uas yuav tsum tau ua cov yeeb yaj kiab zoo, xws li polyvinylpyrrolidone series khoom.
