Abstract
Polyester and polyesteramide alkyds containing no polycycloalkenyl end groups, in admixture with non-resinous vinyl monomers, are flexibilized by inclusion in the mixtures of about 1 to 20 parts by weight of a polyglycol moiety-comprising, vinyl reactive, urethane oligomer per hundred parts of the alkyd.
