ABSTRACT:
A one-component room temperature vulcanizable silicone rubber composition having improved flow characteristics and process for preparing cured silicone rubbers derived therefrom. The one-component silicone rubber compositions consist of a silanol end-stopped linear diorganopolysiloxane base polymer, a filler, an organotriacyloxysilane cross-linker, a catalyst and an organopolysiloxane copolymer consisting of a polysiloxane chain and a polyether chain which are linked together through various carboxyl alkyl radicals. This final component accounts for the improvement in the flow properties of the one-component silicone rubber compositions. In a process for preparing a cured one-component silicone rubber composition, the polysiloxane polyether copolymer is mixed with the diorganopolysiloxane base polymer after which the cross-linker is added and the final mixture exposed to moisture for curing.
