ABSTRACT:
The graft polyester compositions of the invention are especially useful as size compositions since they can be applied to the yarn from a solventless mixture and require only at least one of the application of heat or irradiation to graft polymerize the size in situ on the yarn. The graft polyester of the invention comprises 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.
