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