ABSTRACT:
A substantially non-gelled polymeric composition is disclosed and comprises the reaction product of an A polymer which is an addition polymer having 3.5 or more reactive functional groups per polymer chain and a B polymer having about 2 to about 3 functional groups per polymer chain that are co-reactive with the reactive functional groups of the A polymer. Also disclosed is a process for preparing such polymeric compositions, powder coatings and 100% solids ink resins prepared with such polymeric compositions, and a method for deglossing a powder coating using such polymeric compositions.
