Mo3429CIP PU-364B-CIP NOVEL PROCESS FOR THE PREPARATION OF AMINE-TERMINATED COMPOUNDS The present invention is directed to a process for preparing amine terminated compounds by reacting a polyfunctional acetoacetic acid ester with either ammonia or an organic compound which contains one or more primary amino groups in the presence of a solvent and an acidic catalyst selected from the group consisting of (i) boron trifluoride etherate and (ii) organic acids having pKa values of from 0.1 to 0.8, with the proviso that if the primary amino group containing compound contains no aromatically bound amino groups, the pKa of said organic acid is from 0.1 to less than 0.7.
