Ambient temperature curable silicone rubber compositions
Abstract
Abstract WHERE R" AND R''" ARE ALKYL, ARYL, ALKENYL, OR ARALKYL GROUPS AND RIV IS HYDROGEN OR AN ALKYL, ARYL, ALKENYL OR ARALKYL GROUP, NOT MORE THAN 50% OF THE R3 GROUPS BEING HYDROGEN. R''"-C(-R")(-R"")-COOH ROOM TEMPERATURE CURABLE SILICONE RUBBER STOCKS EXHIBITING IMPROVED REVERSION RESISTANCE AFTER CURING ARE PREPARED FROM MIXTURES OF HYDROXYL ENDBLOCKED DIORGANOPOLYSILOXANES, POLYFUNCTIONAL ORGANOSILICON COMPOUNDS HAVING AT LEAST THREE HYDROCARBONOXY GROUPS PER MOLECULE AND METAL SALTS OF CARBOXYLIC ACIDS WHEREIN THE SALTS ARE PREPARED FROM MONOCARBOXYLIC ACIDS CONTAINING 8 TO 28 CARBON ATOMS PER MOLECULE WHEREIN THE CARBOXYL GROUP IS BONDED DIRECTLY TO A TERTIARY OR QUATERNARY CARBON ATOM. THE METAL SALTS EMPLOYED AS CATALYSTS ARE THUS SALTS OF ACIDS OF THE GENERAL FORMULA
