Patent ID: 8519055

Claim:
A curable polyester, consisting of: i. diacid residues, comprising about 20 to 100 mole percent, based on the total moles of diacid residues, of the residues of isophthalic acid; ii. diol residues, comprising about 10 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 2 to about 40 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.
