    摘要: Organopolysiloxane compositions suitable for use in a liquid injection molding process of elastomeric articles are produced by mixing a vinyl-endblocked polydiorganosiloxane fluid copolymer containing dimethylsiloxane units and methyl-3,3,3-trifluoropropylsiloxane units, a treated, reinforcing silica filler, a platinum-containing catalyst, a curing agent comprising dimethylhydrogensiloxane units as the only source of silicon-bonded hydrogen atoms and, as an inhibitor for the platinum-containing catalyst, certain olefinic siloxanes and/or acetylenic siloxanes. These compositions are especially suited for liquid injection molding because they can be stored at room temperature for days and can be injected into a hot mold with pressures less than 352 kg./sq.cm. (5,000 psi) whereon they cure rapidly to an elastomeric article having a tensile strength greater than 42 kg./sq.cm., and elongation at break greater than 300 percent and a tear strength greater than 7 kg./cm.

    摘要: The present invention relates to the composition, preparation, and use of multi-layer composite films comprising a core layer of low gas permeable material, two intermediate layers sandwiching the core layer, and two outer layers sandwiching the two intermediate layers. The core layer provides the excellent oxygen barrier property, whereas the intermediate and outer layers protect the core layer so the oxygen permeability of the resulting multi-layer composite film becomes independent on relative humidity.

    摘要: A composite films which exhibit low oxygen transmission rates. The film comprises a silane resin coated on a plastic substrate then cured by ultraviolet radiation. For the silane coating, this invention relies on a class of organosilicon compounds derived from 1) organohydrogensilanes or organohydrogensiloxanes and 2) propargyl esters of carboxylic acids containing a terminal aromatic hydrocarbon radical, where the carbopropynoxy group of the ester and the aromatic hydrocarbon radical are separated by at least two adjacent ethylenically unsaturated carbon atoms. If more than two of these carbon atoms are present they form a sequence of conjugated ethylenic double bonds which allows the polymer to cross-link upon exposure to ultraviolet radiation.
