    Abstract: Improved polyurethanes having high tensile strength and modulus, good light stability, good blocking characteristics and that are soluble in inexpensive solvents are obtained by reacting together a hydroxyl-terminated polyester, a poly(epsiloncaprolactone)diol, an aliphatic diol containing at least 5 carbon atoms, a hydroxyl-terminated dimethyl polysiloxane and an acyclic or alicyclic diisocyanate.

    Abstract: POLYURETHANES PREPARED FROM POLY(EPSILON-CAPROLACTONES) HAVING MOLECULAR WEIGHTS FROM ABOUT 1800 TO ABOUT 2200, LESS THAN ONE MOL OF AN ALIPHATIC GLYCOL AND CERTAIN AROMATIC DIISOCYANATES FROM ADHESIVE MATERIALS WHICH ARE SOFT AND TACKY WHEN HEATED BUT WHICH ON AGING HARDEN AND CRYSTALLIZE TO FORM TOUGH, CRYSTALLINE BUT FLEXIBLE, BONDING AGENTS HAVING GOOD ADHESIVE PROPERTIES. THE POLY(LACTONEURETHANES) ARE PARTICULARLY ADAPTABLE TO PROVIDING ARTICLES ADHERED TOGETHER WITH EXCELLENT STRUCTURAL STABILITY.
