Novel reactions of bicyclic amide acetals with reactive protic compounds

Blends of polyamide polyols and urethane diols are prepared by reacting alkyl (methyl) esters of polybasic acids (preferably dibasic acids) with excess alkanolamine (preferable ethanol amine propanol amine) to form the polyamide polyol of the polybasic acid and alkyl alcohol.
