    • 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.
    • 羧酸酰胺聚合物和含有它们的涂料组合物对于食品和饮料容器的涂覆特别有用。 羧化酰胺聚合物是(1)下式化合物的反应产物:其中A是由聚环氧化物上的1,2-环氧基与氨或胺的开环反应得到的有机残基,R1是 氢或C1-4烷基,R2是C2-12亚烷基,x是0或1,y是0-4,R3是氢或C1-6烷基,R4是氢或C1-6 烷基,提供至少一个R 1,R 3或R 4为氢,n为至少1.0,(2)二元羧酸的环状酸酐。 羧化酰胺聚合物可以通过用有机或无机碱中和聚合物制成水可稀释并用于水性涂料组合物中。
