  • Synthesis and characterization of novel cyclosiloxanes and their self- and co-condensation with silanol-terminated polydimethylsiloxane
    Patent number: 7569652
    Abstract: The present invention is directed to syntheses of cyclolinear networks. Two novel cyclic siloxanes were used as starting materials. The cyclic siloxanes are self-condensed and co-condensed with silanol-terminated polydimethylsiloxane to vinyl-terminated cyclolinear polymers. Cyclolinear networks can be synthesized by hydrosilylation of vinyl-terminated cyclolinear polyorganosiloxanes with a copolymer of dimethylsiloxane and methylhydrosiloxane.

  • Method and Apparatus For Determining the Oxygen Permeability of a Polymer
    Publication number: 20080233006
    Abstract: The present invention is relates to an apparatus and method for the determination of the oxygen gas permeability of a polymer. In one embodiment, the present invention relates to an apparatus and method for determining the oxygen gas permeability of a polymer membrane (e.g., a polydimethylsiloxane and/or polysiloxane polymer or copolymer). In still another embodiment, the present invention relates to oxygen gas permeable polymer compositions.

  • Amphiphilic Co-Networks, Films Made From Amphiphilic Co-Networks and Uses for Such Co-Networks and Films
    Publication number: 20080051513
    Abstract: The present invention relates to the production of amphiphilic copolymer networks or co-networks that are both hydrophobic and hydrophilic, the copolymer networks comprise polyalkylene glycol segments and disubstituted polysiloxane segments. Furthermore, the present invention relates to products and/or films made from the amphiphilic copolymer networks or co-networks produced in accordance with the synthesis methods of the present invention. In one embodiment, amphiphitic networks or co-networks are synthesized using functional multiblock co-polymers according to the formula (AY)x(BY)y, where A represents an alkylene glycol polymer having n repeating alkylene glycol units, B represents a disubstituted siloxane polymer having m repeating siloxane units, and Y represents a molecule (e.g., a silane) that functions both as a chain extender and a crosslinker.
