Abstract: Epoxy resin is reacted with a terminating agent to eliminate at least part of the epoxide groups of the resin and form modified resin. The epoxy resin or such modified resin is also reacted with addition polymerizable monomer at elevated temperature in the presence of at least 3% of benzoyl peroxide based on the weight of such monomer. Generally the latter reaction is done at about 110.degree. C. to about 120.degree. C. These two reactions can be performed in any desired sequence, or simultaneously. The final reaction mixture produced contains:(a) graft polymer;(b) ungrafted, modified resin; and(c) ungrafted addition polymer, formed associativelywith the graft polymer. The invention is useful for making coating compositions. The compositions have good weather resistance and are particularly useful for making sanitary coatings for cans for foods and beverages, especially for beer.

The aqueous reaction mixture for polymerization contains both a cosolvent in proportions low enough to avoid formation of a solution of the polyelectrolyte in the final aqueous medium and an ionizing agent sufficient to ionize at least about 0.0001 neutralization equivalent of said ionizable monomer. The polyelectrolyte has a mean weight average not substantially in excess of 100,000 molecular weight.

Abstract: Discloses a technique for modifying an epoxy resin by reacting with addition copolymerizable monomer in the presence of at least 3% of benzoyl peroxide at about 110.degree. C. to 120.degree. C., or the free radical initiating equivalent thereof. The reaction mixture obtained contains:(a) unreacted epoxy resin;(b) graft polymer; and(c) associatively formed but ungrafted addition polymer.The graft polymer is formed from the epoxy resin by the grafting of addition polymer onto aliphatic backbone carbons of the epoxy resin, such grafting being at carbons that have either one or two hydrogens bonded thereto in the ungrafted state. The process is useful for making polymer blends for coating compositions, and particularly, coatings for cans for foods and beverages, especially for beer. The coating compositions may be aqueous dispersions ready for spray application, or concentrate that can be made up readily into aqueous sprayable coating compositions. Solvent vehicles may also be used.
