Abstract

A resin dispersion suitable for sizing paper is prepared by dissolving maleic acid or anhydride or fumaric acid in molten rosin, adding an alkaline material and water, and heating to 150-500 DEG C. under a pressure of 250-1000 lb./sq. in. The alkaline material, which may be caustic soda, soda ash, ammonia, mono-ethanolamine, morpholine or trisodium phosphate, is preferably in sufficient quantity to yield products having acid numbers between +35 and - 10. Reaction time is from 30 secs. to 60 mins. The rosin preferably contains less than 0.2 per cent volatile ingredients, and is reacted, per mol., with 0.05 to 0.7 mol. of acid. The final dispersions contain 40-80 per cent solids. Specification 755,149 is referred to.
