PROCESS FOR THE PREPARATION OF TRIALKYLSILYLATED CARBOXYLATE MONOMERS, THE OBTAINED TRIALKYLSILYLATED CARBOXYLATE MONOMERS AND THEIR USE IN ANTI- FOULING COATINGS

摘要

The invention relates to a process for the preparation of trialkylsilylated carboxylate monomers of general formula (I) which process comprises the step of reacting a hexaalkyldisilylsulfate of the formula (IV) with an unsaturated carboxylic compound of formula (III) and the obtained compounds. The invention further relates to a process for the preparation of a hexaalkyldisilylsulfate of the formula (IV) by treating a hexaalkyldisiloxane of formula (II) with fuming sulfuric acid, and the obtained compounds. The invention further relates to the use of said compound (I) in the preparation of a hydrolysable polymer.
