ABSTRACT:
The compatibility between high consistency fluorinated and non-fluorinated polydiorganosiloxanes is increased, with a resultant increase in the physical-properties of elastomers prepared from mixtures of these polymers, by blending the polymers together with a reinforcing silica filler that is reacted with both fluorinated and non-fluorinated liquid polydiorganosiloxanes as filler treating agents. The high consistency polydiorganosiloxanes contain at least two alkenyl radicals per molecule and are cured by a hydrosilation reaction.
