Abstract
A cross-linked graft polyester comprising the reaction product of an aminoplast and a graft polyester, said graft polyester comprising the reaction product of (1) an unsaturated polyester which is the reaction product of at least one polycarboxylic acid reactant, preferably a dicarboxylic acid reactant and at least one polyhydric alcohol reactant, preferably a diol, wherein a minor effective proportion of at least one of said reactants is .alpha.,.beta.-ethylenically unsaturated with (2) at least one monovinyl monomer reactant comprising at least one acidic monovinyl monomer containing at least one carboxyl group or a mixture of said vinyl monomer with any monovinyl monomer.
Claims9
A cross-linked graft polyester comprising the reaction product of an aminoplast resin and a graft polyester having free carboxyl groups forming an integral part of the graft polyester chain, said polyester comprising the reaction product of
- I. an unsaturated polyester comprising the reaction product of:
- (a) at least one polycarboxylic acid reactant comprising (1) a dicarboxylic acid reactant selected from the group consisting of dicarboxylic acids, corresponding dicarboxylic anhydrides, dicarboxylic acid, esters, and their corresponding acyl halides or (2) a mixture of said dicarboxylic acid reactant with up to 20 mole percent of a polycarboxylic acid reactant having a functionality greater than two based upon 100 mole percent of said dicarboxylic acid reactant and
- (b) at least one polyhydric alcohol reactant comprising (1) a diol or (2) a mixture of a diol and up to 20 mole percent of a polyhydric alcohol having a functionality greater than two based upon 100 mole percent of said polyhydric alcohol,
- wherein a minor effective proportion of said dicarboxylic acid reactant or polyhydric alcohol reactant is alpha,beta-ethylenically unsaturated and
- II. an least one monovinyl monomer reactant comprising at least one monovinyl monomer having at least one carboxylic group or a mixture of said vinyl monomer with any monofunctional vinyl monomer.
