Abstract
Abstract A polymer capable of self-curing or cross-linking at room temperature is produced by free radical polymerization in a nonprotonic solvent of: A. i. a combination of (a) at least one ethylenically unsaturated compound having an epoxy group and (b) at least one ethylenically unsaturated compound having a tertiary amino group selected from the group consisting of an N,Ndisubstituted amino group, a pyridyl group, a quinolyl group and an isoquinolyl group or II. AT LEAST ONE ETHYLENICALLY UNSATURATED COMPOUND HAVING ONE EPOXY GROUP AND ONE TERTIARY AMINO GROUP SELECTED FROM THE GROUP CONSISTING OF AN N,N-disubstituted amino group, a pyridyl group, a quinolyl group and an isoquinolyl group, and optionally B. at least one free radical-copolymerizable ethylenically unsaturated compound other than the ethylenically unsaturated compounds (i) and (ii) and which is free of active hydrogen atoms.
