Fluid, stable polymer-polyols are provided which consist of an organic polyol medium and an interpolymer of a minor amount of polymerized ethylenically unsaturated dicarboxylic acid anhydride, such as maleic acid anhydride, and a major amount of at least one different polymerized ethylenically unsaturated monomer, the interpolymer being in the form of particles that are stably dispersed in the polyol. Polyurethane foams produced from these polymer/ polyols display improved load bearing and compression set when compared with polymer/polyols produced in a similar manner without the ethylenically unsaturated dicarboxylic acid anhydride: elastomers so produced have improved tensile modulus and tear properties.

There are disclosed graft polyesters useful as adhesives and coatings and especially useful in processes for sizing spun and continous filament synthetic organic and inorganic fibrous yarn. One embodiment of the invention is a textile size composition having free carboxyl groups which is prepared in situ on a textile yarn by the application of heat or radiation to a mixture of an unsaturated polyester reactant and a monovinyl monomer reactant comprising an acidic monovinyl monomer having at least one carboxyl group or mixtures thereof with any monovinyl monomer.
Desizing can be accomplished by partial neutralization of the size to a pH of at least 6 by reacting the size with a base to render the graft polyester water-dispersible or water-soluble.
Also disclosed are cross-linked graft polyesters obtained by reacting an unsaturated polyester with at least one polyunsaturated vinyl monomer.
