Poly Vinyl Caprolactam Synthesis

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

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. Fabrication of thermo responsive cotton fabrics using poly vinyl caprolactam co hydroxyethyl acrylamide copolymer. 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.
