| Abstract | 57 ABSTRACT A new method of producing a silicone rubber composi tion yields a unique composition. When the composition is further mixed with extending filler and vulcanized, the tensile strength of the vulcanized silicone rubber is improved over that obtained when the composition is not produced following the method of this invention. The method mixes polydiorganosiloxane gum, treated reinforcing silica filler, a portion of hydroxylated or ganosilicon compound having an average of from 1 to 20 percent by weight hydroxyl radicals and an average of from 1 to 31 percent by weight vinyl radicals; heating the mixture; then cooling and admixing another portion of the hydroxylated organosilicon compound. |
