Abstract
(EN)
The invention concerns organopolysiloxane compositions obtainable by the following successive steps: step 1: reacting (i) at least a linear diorganopolysiloxane reagent A comprising a hydroxyl group at each chain end; (2i) and at least a hydroxyl organopolysiloxane resin B having a weight content of hydroxyl group ranging from 0.1 to 10 %; (3i) with at least a polyalkkoxysilane C; step 2: introducing in the medium of step 1 (6i) a mineral filler G based on amorphous silica and (7i) an efficient amount of a catalyst H consisting of at least one titanium organic derivative; step 3: the resulting mixture is subjected to devolatilization carried out at a pressure less than atmospheric pressure.
