A polyesteramide comprising:
- (a) a diamine component comprising:
- 30-50 mole % of diamine residues derived from diamine which is CH2((C3-8)cycloalkyl-NH2)2;
- (b) a diol component comprising:
- 50-70 mole % of diol residues derived from a diol which is (C3-8)cycloalkyl di((C1-3)alkanol);
- and
- (c) a diacid component comprising:
- 10 to 100 mole % of diacid residues derived from a diacid that is the combination of HO2C-(C2-40)alkylene-CO2H and HO2H and HO2C-(C3-10)cycloalkyl-CO2H, or HO2C-(C3-10)cycloalkyl-CO2H;
- wherein each cycloalkyl is unsubstituted or substituted by 1-4 (C1-3)alkyl,
- wherein the total mole % of the diacid component is 100 mole %, and wherein the total mole % of the combined diol and diamine component is 100 mole %1 wherein the polyesteramide further comprises branching agent residues derived from a compound chosen from trimellitic acid, trimethylolpropane, trimethylolethane, glycerol, pentaerythritol, citric acid, tartaric acid, 3-hydroxyglutaric acid, glycerineerythritol, threitol, dipentaerythritol, sorbitol, trimellitic anhydride, pyromelltic dianhydride, trimesic acid or dimethylol propionic acid.
