Abstract:
1. A curable polyester, comprising: i. diacid residues, comprising about 30 to about 70 mole percent, of the residues of isophthalic acid and about 70 to about 30 mole percent of the residues of adipic acid, based on the total moles of diacid residues; ii. diol residues, comprising about 50 to 100 mole percent, based on the total moles of diol residues, of the residues of 2,2,4,4-tetramethyl-1,3-cyclobutanediol; and iii. polyol residues, comprising about 3 to about 30 mole percent of the residues of at least one polyol, based on the total moles of diol and polyol residues; wherein said curable polyester has a number average molecular weight of about 500 to about 10,000 daltons, a glass transition temperature of about −35° C. to about 50° C., a hydroxyl number of about 20 to about 300 mg KOH/g of polyester, and an acid number of 0 to about 80 mg KOH/g of polyester.
