## Abstract Despite its being weaker base poly(2‐vinylpyridine) polymerized DL‐β‐phenylalanine NCA at a much faster rate than pyridine and α‐picoline. Poly(2‐vinylpyridine) adsorbs NCA by hydrogen bonding with the cooperation of a few pyridine groups. This results in a high local concentration of N
A study of the effect of catalyst (base) concentration and N-acylcaprolactam cocatalyst size and substitution on the fast anionic polymerization of caprolactam indicated that a steric effect due to cocatslyst size exists, and perhaps an electronic effect due to cocatalyst substitution was noted. The
