  • Patent number: 6265514
    Abstract: Poly(siloxane-acrylate) elastomers with low weep characteristics are formed by the steps of: (A) forming an amine functional alkenyl-containing siloxane by mixing and heating: (a) a polydiorganosiloxane, (b) an amino-functional silane hydrolyzate, (c) an alkenylorganosiloxane, and (d) a base equilibration catalyst, then (B) reacting, at room temperature, the amine functional alkenyl-containing siloxane with an acrylate to form a curable alkenyl-containing poly(siloxane-acrylate) with oxycarbonylethyleneimino-containing organic groups, and (C) curing the alkenyl-containing poly(siloxane-acrylate) to form an poly(siloxane-acrylate) elastomer.

  • Patent number: 5777047
    Abstract: Organosiloxane compositions curable to silicone elastomers having improved weep properties are described. The compositions include an alkenyl-containing polydiorganosiloxane, an organohydrogensiloxane, a platinum-group metal catalyst and a MQ-type resinous organosiloxane copolymer having at least one fluorine atom-containing group per molecule; and a silicone elastomer prepared from such composition. A method of minimizing the leakage of a hydrocarbon fluid from a container using the silicone elastomer is also described.
