Abstract

Disclosed are polyesteramide resin compositions having amide units of formula (I): ##STR1## and the units of the formula (II): ##STR2## wherein the polyesteramide is substantially devoid of units derived from butane diol. The ratio of (I) to (II) in the polyesteramide is preferably less than 1:3. Preferred polyesteramides have at least 80% of units of formula (I) separated by at least one of the units of formula (II).
