Chemical description n vinyl 2 pyrrolidone abbr nvp cas no. N vinyl 2 pyrrolidone nvp cas 88 12 0 is a clear to slightly yellow liquid crystallization under 13 it s easy to hydrolyze and polymerize itself but it can remain as liquid at room temperature for extended periods. It is the precursor to polyvinylpyrrolidone pvp an important synthetic material. C 6 h 9 no.

Reactive and susceptible to hydrolyzation and polymerization. N vinylpyrrolidone nvp is an organic compound consisting of a 5 membered lactam linked to a vinyl group it is a colorless liquid although commercial samples can appear yellowish. Specification no tests specification 1 purity ge 99 5 2 denstiy g ml 1 03 1 04 3. Poly n vinyl 2 pyrrolidone pvp is a polar brittle water soluble glassy polymer that is readily plasticized by humidity.

Bpa 10 ppm n n di sec butyl p phenylenediamine applications. The base catalyzed reaction with acetylene. For pharmaceuticals cosmetics and food additives or copolymers used as viscosity improvers in oils and in water borne paints and adhesives. This plasticization causes hairsprayed hair to droop in humid atmospheres.

Soluble in water and a variety of organic solvents. Poly vinyl acetate pva in contrast is a soft water insoluble nonpolar polymer that resists removal by shampoo. 88 12 0 molecular and structural formula c 6 h 9 no characteristics a colorless to slightly yellowish transparent liquid.
