Poly Vinyl Caprolactam Synthesis

The use of pnvcl instead of pnipam is considered advantageous because of the assumed lower toxicity of pnvcl.

Synthesis of graft copolymer the graft copolymer derived from vcl and naalg was prepared by free radical polymerization. Form p crystalline hysical state c liquid olor light yellow odor d characteristic ensity.

However reported with a high dispersity đ the synthesis in water and water containing systems also results in high molecular weight pnvcl but the size exclusion chromatograms show broad distributions bimodal distributions and second distributions as shoulders indicate a poor control of polymerization. Briefly 0 25 g of naalg.

Bulk ordering pricing. Caprolactam was first described in the late 1800s when it was prepared by the cyclization of ε aminocaproic acid the product of the hydrolysis of caprolactam.
