ABSTRACT:
Polyorganosiloxanes that are curable to crosslinked solid material, at ambient temperature upon exposure to gaseous oxygen, wherein the polyorganosiloxane contains, per molecule, at least one monovalent olefinically polyunsaturated organic radical containing at least one 1,3-pentadienylene group or 1,4-pentadienylene group bonded to silicon through silicon-to-carbon bond and wherein any remaining valence of silicon is satisfied by a silicon-to-oxygen-to-silicon bond or by a monovalent organic radical free of more than one olefinically unsaturated group per monovalent organic radical, which monovalent organic radical is bonded to silicon by a silicon-to-carbon bond. Compositions are also described containing the novel polyorganosiloxanes, suitable driers either chemically combined in the polyorganosiloxane or physically mixed therewith. The compositions can also contain fillers, plasticizers and/or catalyst activators.
