ABSTRACT:
Non liquid-crystalline esterphenol-capped liquid polymer and polyol compositions in combination with an amino crosslinking agent endow coating compositions containing them with the ability of providing films having superior properties. The esterphenol-capped polymers and polyols can be prepared by direct esterification of hydroxybenzoic acid without its decarboxylation.
