Abstract: The copolymers are made from (A) 3-60 wt.% alpha, beta-unsat. carboxylic acids with 3-5 C atoms, (B) 40-97 wt.% esters of such acids, (C) 0-40% other monomers with C=C bonds, (D) 4-20% water soluble alkanols, alkane diols, ketones and/or carbonamides, and (E) 0-10% water. Polymerisation is at 60-100 degrees C using usual water-insoluble radical initiators, giving highly concentrated solns. which are neutralised with diluted alkalis or ammonia to a copolymer content of 25-60 wt.%. Remaining amounts of (D) may be wholly or partly removed e.g. by distillation. The copolymer solns. are suitable as sizes for fibres and yarns, and have relatively low viscosities. They resist swelling and are almost insoluble in water at 20-30 degrees C, but dissolve in dilute alkali solns.
