ABSTRACT:
A hydroxy-terminated linear carbonate is produced by reacting a cyclic alkylene carbonate such as neopentyl glycol carbonate with a substance having at least one alcoholic hydroxyl group in the presence of a catalyst. Mono- or polyhydric alphatic alcohols, polycaprolactone polyols, hydroxyl group-containing acrylic monomers and polymers, and polyester polyols are modified by the reaction with the cyclic alkylene carbonate to have an enhanced reactivity and resistance to hydrolysis.
