ABSTRACT:
N-(aminomethyl)-.alpha.,.beta.-ethylenically unsaturated carboxamides such as N-(dimethylaminomethyl)acrylamide are readily prepared without coincident production of saturated impurities by reacting an .alpha.,.beta.-ethylenically unsaturated carboxamide such as acrylamide with a lower aldehyde such as formaldehyde and a secondary amine such as dimethylamine at a pH below 7. The resulting aminomethyl carboxamides are polymerized at a pH of 7 or less to form polymers containing essentially no gelled product.
