  • MULTILAYER FILMS INCLUDING THERMOPLASTIC SILICONE BLOCK COPOLYMERS
    Publication number: 20070177272
    Abstract: A multilayer film includes a first layer of a first polymeric material and a second layer of a second polymeric material. The first material has a first index of refraction and the second material has a second index of refraction less than the first index of refraction. In one embodiment, the second material includes a polydiorganosiloxane polyamide block copolymer. In another embodiment, the second material includes a polydiorganosiloxane polyoxamide block copolymer.

  • Adhesive compositions
    Publication number: 20070148475
    Abstract: Polydiorganosiloxane polyoxamide, linear, block copolymers and methods of making the copolymers are provided. The method of making the copolymers involves reacting a diamine with a polydiorganosiloxane precursor having oxalylamino groups. The polydioroganosiloxane polyoxamide block copolymers are of the (AB)n type.

  • Polydiorganosiloxane polyoxamide copolymers
    Publication number: 20070148474
    Abstract: Polydiorganosiloxane polyoxamide, linear, block copolymers and methods of making the copolymers are provided. The method of making the copolymers involves reacting a diamine with a precursor having at least one polydiorganosiloxane segment and at least two oxalyamino groups. The polydiorganosiloxane polyoxamide block copolymers are of the (AB)n type.
