摘要：
Ungelled hydroxyl-containing oligomers and their method of preparation are disclosed. The oligomers can be prepared by reacting an organic isocyanate with a half-ester formed from reacting a polyol with a 1,2-dicarboxylic acid anhydride followed by reaction with an epoxide. The oligomers are useful as resinous binders in high solids coating compositions. The coating compositions can be applied by spraying and do not result in a tacky overspray common with many high solids coating compositions.
