  • Patent number: 6548590
    Abstract: Composites which include a polymer matrix having natural free volume therein and an inorganic or organic material disposed in the natural free volume of the polymer matrix are disclosed. In addition, methods for making a composite are described. A polymer matrix having free volume therein is provided. The free volume is evacuated, and inorganic or organic molecules are infused into the evacuated free volume of the polymer matrix. The inorganic or organic molecules can then be polymerized under conditions effective to cause the polymerized inorganic or organic molecules to assemble into macromolecular networks. Alternatively, where the polymer matrix contains a functionality, the inorganic or organic molecules can be treated under conditions effective to cause the inorganic or organic molecules to interact with the polymer matrix's functionality.

  • Patent number: 6489385
    Abstract: A highly saturated nitrile group-containing copolymer rubber having a Mooney viscosity lowered by 15 points or more by applying a high shearing force thereto in the presence of an aging inhibitor, which has a Mooney viscosity of 5-35 and a weight average molecular weight/number average molecular weight ratio of 3-5, and exhibits an increase in Mooney viscosity of 10 points or fewer while the rubber is allowed to stand in the air at room temperature for 30 days. The viscosity of the copolymer rubber changes only to a minor extent with the lapse of time, and the copolymer rubber has excellent processability and storage stability. The copolymer rubber can be used as a heat-resistant rubber composition comprising the copolymer rubber and other heat-resistant rubber. The copolymer rubber can be used as a composite thereof with a fiber, which has good mechanical strength.

  • Patent number: 6040366
    Abstract: The compression set of elastomeric silicone compositions, addition cured injection moldable compositions, is reduced by the incorporation of nitrogen compounds wherein the nitrogen possesses at least one organic substituent and the nitrogen is tetravalent wherein the nitrogen is cationic. The adhesion of such compositions to thermoset or thermoplastic polymer substrates is improved by the addition of bis(trimethoxysilylpropyl)fumarate and a disilanol that may or may not contain alkenyl groups. The lubricity of such compositions is improved by the addition of compounds selected from the group consisting of diorganosiloxanes such as polydimethylsiloxanes, phenyl containing siloxanes such as copolymers of diphenylsiloxane with diorganosiloxanes and copolymers of methylphenylsiloxane with diorganosiloxanes, fluorosilicones such as silicones containing trifluoropropyl substituted siloxanes, polydimethylsiloxanes, aliphatic and aromatic hydrocarbons that are liquid between 0.degree. C. and 100.degree. C.
