Compositions useful for textile sizes which contain anhydride based graft copolymers. The anhydride based graft copolymers are the reaction product of an ethylenically unsaturated monomer, an anhydride monomer selected from malefic anhydride and itaconic anhydride, either a monofunctional polyglycol having a hydroxyl or amine terminal group or a polyfunctional polyglycol having a weight average molecular weight of greater than 5,000 and at least one terminal hydroxyl group, and a free radical initiator. The anhydride based graft copolymers provide lubrication during sizing and a thorough removal of waxes and oils during desizing and scouring.
