摘要: Organosilicon compositions comprising at least one silicon-bonded alkenyloxy radical, such as vinyldimethylcarbonoxy, are disclosed. These unsaturated organosilicon compositions are useful as partial or complete replacements for the analogous organosilicon compositions bearing the well-known silicon-bonded vinyl radical. In particular, vinyldimethylcarbinoxy-endblocked polydimethylsiloxane is useful as a component in an elastomeric composition which is cured with an organosilicon hydride.

摘要: A composition curable to a silicone elastomer is prepared by mixing a triorganosiloxy endblocked polydimethylsiloxane fluid where the triorganosiloxy is dimethylvinylsiloxy or methylphenylvinylsiloxy, a reinforcing silica having a surface treated organosiloxane groups which contain 0.05 to 0.32 percent by weight vinyl, a fluid organohydrogensiloxane, a platinum catalyst and optionally a platinum catalyst inhibitor. The polydimethylsiloxane fluid has a major peak molecular weight of 68,000 to 135,000, a dispersity index greater than 3.8, the lowest molecular weight species between 854 and 3146 and the highest molecular weight species between 174,000 and 370,000. These compositions are readily extrudable under low pressure and cure to high strength elastomers with a high durometer.

摘要: An improved treatment for reinforcing silica uses both a silazane represented by the formula (RR'R"Si).sub.2 NH and bis-Si-(1-methyl-1-silacyclopentenyl) amine as filler treatment. The filler treatment may be done either in situ during the manufacture of curable silicone elastomer compositions or as a separate operation. The treatment allows production of an easily extrudable composition with improved durometer and tear strength.

摘要: A fluorosilicone rubber with low compression set and other physical properties which are either are not significantly effected or are improved are made by curing a composition of a polydiorganosiloxane having 3,3,3-trifluoropropylsiloxane units and endblocked with vinyl or silacyclopentenyl groups, a reinforcing silica having dimethyl(3,3,3-trifluoropropyl)siloxy units as the surface treatment, and a vinyl specific organic peroxide. The polydiorganosiloxane endblocking is done by reacting a silanol endblocked polymer with a silazane.

摘要: Vinyl and allyl containing bis(polydimethylsiloxanyl)amine compounds are useful as a treating agent for pinely divided silica when used in conjunction with conventional silazanes. The in situ filler treatment using the amine compounds and silazanes allows the production of easily extrudable compositions which cure to silicone elastomers with unique property profiles.
