Hi, I have got some 1-Vinyl-2-Pyrrolidone, I was wondering if this could be converted to an epoxy pyrrolidone. My concern is that epoxies frequently
use amines as catalysts, would the nitrogen in the ring initiate polymerisation as the epoxy forms? Also I was thinkng of using a peroxyacetic acid to
form the epoxy, would this be ok?

Epoxy resins cure by reacting and opening the epoxy ring and some active hydrogen compound - typically hydroxy groups with base (amines) or Lewis acid
catalysts. 1-Vinyl-2-Pyrrolidone has no active hydrogens, and can't react that way; on top of that it is an amide and less basic than an amine.

I understand why you're calling in an amide... due to the proximate carbonyl..but it's really a lactam. It's thought to be carcinogenic in some
circles so handle with care.

A lactam is a cyclic amide, so it is both, just like lactones are esters and you are a mammal.
