Abstract
A graft sulfonated polyester. A stock or sulfonated polyester carries grafts derived from a monomeric composition based on (a) at least one carboxylic acid unsaturated through ethylene, (b) butylacrylate or a mixture of monomers containing from 60-70% by weight of butyl acrylate and (c) at least one carboxylic acid ester, unsaturated through monoethylene. The graft sulfonate polyesters are prepared by polymerizing the monomeric composition in the presence of a water dispersible sulfonated polyester. Aqueous dispersions or aqueous solutions of the graft sulfonated polyesters may be used for sizing textile threads and fibers.
