    摘要： Carboxylated amide polymers and coating compositions containing same are especially useful for the coating of food and beverage containers. The carboxylated amide polymers are the reaction product of (1) a compound of formula: ##STR1## wherein A is the organic residue resulting from a ring opening reaction of a 1,2-epoxy group on a polyepoxide with ammonia or amine, R.sub.1 is hydrogen or a C.sub.1-4 alkyl group, R.sub.2 is a C.sub.2-12 alkylene group, x is 0 or 1, y is from 0 to 4, R.sub.3 is hydrogen or a C.sub.1-6 alkyl group, R.sub.4 is hydrogen or a C.sub.1-6 alkyl group, provided at least one R.sub.1, R.sub.3 or R.sub.4 is hydrogen, and n is at least 1.0 with (2) a cyclic anhydride of a dibasic carboxylic acid. The carboxylated amide polymers can be made water reducible by neutralizing the polymer with an organic or inorganic base and used in aqueous coating compositions.
