Abstract
At least one (meth)acrylate is reacted with a heterocyclic alcohol (III) in the presence of at least one catalyst chosen from dialkyltin oxides and dialkyltin dialkoxides. Alkylimidazolidone acrylates and methacrylates are known for the part they play in the constitution of polymers which can be used as coatings and adhesives and for the treatment of paper and textiles, and for their use as agents for the treatment of leather and in the production of emulsion paints. ##STR1## R.sub.1 =H, CH.sub.3 ; A, B=straight or branched chain alkylene group containing from 2 to 5 carbon atoms.
Claims24
A process for the preparation of a compound of formula I:
- ##STR5## wherein:
- R.sub.1 is hydrogen or methyl, and
- A and B are each a straight- or branched chain alkylene group containing 2 to 5 carbon atoms, by reaction of at least one (meth)acrylate of formula II:
- ##STR6## wherein R.sub.1 has the above-mentioned meaning and R.sub.2 is an alkyl radical containing from 1 to 4 carbon atoms, with a heterocyclic alcohol of formula III:
- ##STR7## wherein A and B have the above-mentioned meaning, in the presence of a catalytic quantity of at least one catalyst which is a dialkyltin oxide, a dialkyltin dialkoxide, or a dialkyltin diester or mixtures thereof.
