Application

NVCL forms a temperature responsive polymer, which can be used for a variety of biomedical applications.

General description

N-Vinylcaprolactam (NVCL) is an organo-soluble amphiphilic material that is soluble in solvents like benzene, isobutanol, and isopropanol. It can be used in the preparation of poly(NVCL) by free-radical polymerization at a temperature higher than its melting point.

Poly(N-vinylcaprolactam) (PNVCL) and poly(N-vinylcaprolactam-co-acrylic acid) (poly(NVCL-co-AA)) were synthesized by solution-free radical polymerization and displayed thermo-responsive behavior, with lower critical solution temperatures (LCSTs) of 35 °C and 39 °C, respectively. The incorporation of AA unities made the poly(NVCL-co-AA) sensitive to both pH and

The thermosensitive polymers of N-vinylcaprolactam P1, P2, P3, P4, and P5 were synthesized via the surfactant free precipitation polymerization (SFPP) at 70 °C in the presence of cationic initiator 2,2'-azobis[2-methylpropionamidine] dihydrochloride (AMPA). The influence of various concentrations of initiator AMPA
