Adhesive compositions with polyesters comprising 2,2,4,4-tetraalkyl-1,3-cyclobutanediol and methods of making the same

A hot melt adhesive composition, said adhesive composition comprising:

• a polyurethane prepolymer comprising residues of (i) at least one polyester polyol comprising a diol component having residues of 2,2,4,4-tetraalkyl-1,3-cyclobutanediol (TACD) and (ii) at least one isocyanate,
• wherein at least one property of said adhesive selected from the group consisting of green strength, heat resistance, and hydrolytic stability is at least 5 percent higher than the same property exhibited by an identical adhesive composition formed with a polyurethane prepolymer having an identical composition as said polyurethane prepolymer, but having residues of a comparative polyester polyol instead of said polyester polyol, wherein said comparative polyester polyol has an acid component comprising 50 mole % terephthalic acid (TPA) and 50 mole % isophthalic acid (IPA) and a diol component comprising 52 mole % neopentyl glycol (NPG) and 48 mole % ethylene glycol with a hydroxyl number of 45 mg KOH/g, a glass transition temperature of 50° C., and a melt viscosity of 130° C. at 60 Pa·s, all other components being the same.
