Abstract
The present application discloses novel polyesteramides comprising cycloalkyl diols and/or cycloalkyl dialkanols with tunable properties based on the monomers and monomerratios used to prepare the polyesteramides and varying the reaction conditions. The present application also discloses compositions and articles.
Claims20
A polyesteramide comprising:
- (a) a diamine component comprising:
- 1 to 99 mole % of diamine residues derived from a diamine selected from the group consisting of CH2((C3-8)cycloalkyl-NH2)2, H2N—((C1-3)alkyl)0-1-(C3-8)cycloalkyl-((C1-3)alkyl)0-1-NH2, 6- to 8-membered heterocyclyl containing 2 nitrogen heteroatoms, H2N—((C1-3)alkyl)0-1-(C6-10)bicycloalkyl-((C1-3)alkyl)0-1-NH2 wherein the bicycloalkyl is unbridged or bridged, and combinations;
- (b) a diol component comprising:
- 1 to 99 mole % of diol residues derived from a diol which is selected from the group consisting of cyclobutane-1,3-diol, 2,4-dimethylcyclobutane-1,3-diol, 2,4-diethylcyclobutane-1,3-diol, 2,2-dimethylcyclobutane-1,3-diol, and 2,2,4,4-tetramethylcyclobutane-1,3-diol;
- and
- (c) a diacid component comprising:
- 10 to 100 mole % of diacid residues derived from a diacid selected from the group consisting of HO2C—(C2-40)alkylene-CO2H, HO2C—(C3-10)cycloalkyl-CO2H, and combinations;
- 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 %.
