Abstract:
The present invention is in the preparation of methacrylic or acryloxyalkylalkoxysilanes by the reaction at a temperature of from 80.degree. and 130.degree. C. of an alkali (meth) acrylate with a halogen alkylalkoxysilane in the presence of a quaternary ammonium salt which has long-chin alkyl moieties, in which the sum of all carbon atoms is between 10 and 40 as a phase-transfer catalyst. In the new procedure no solvents need to be used. The yields are better than 95%.
