Application

ε-Caprolactam can be used as a precursor for the production of nylon-6 by ring-opening polymerization.It is also microwave irradiated with ε caprolactone in the presence of an anionic catalyst to yield poly(ε caprolactam-co-ε-caprolactone).

Temperature and glucose sensitive microgels were prepared via radical precipitation polymerization, using N-vinylcaprolactam (NVCL) as the main monomer, N,N-methylenebisacrylamide (MBA) as a crosslinker, V50 as initiator and 4-vinylphenylboronic acid (VPBA) as a functional monomer. The LCST of homopoly (NVCL) was
