Abstract: A composite membrane comprising (i) a polymeric membrane panel, said panel having first and second planar surfaces; (ii) a cross-linked adhesive layer disposed on said first planar surface of said polymeric membrane panel, said cross-linked adhesive layer having first and second planar surfaces, where said first planar surface of said cross-linked adhesive layer is in contact with said first planar surface of said polymeric membrane panel; and (iii) an optional release member disposed on said second planar surface of said cross-linked adhesive layer, where said polymeric membrane panel includes a functionalized polymer at said second planar surface.

Abstract: The present invention relates to a polymer composition comprising: (a) poly(butylene terephthalate); (b) glass fibres; (c) a polymer comprising moieties derived from acrylonitrile, butadiene and styrene; and (d) a polymer comprising moieties derived from ethylene, methyl (meth)acrylate and glycidyl (meth)acrylate. Such polymer composition provides a desired balance of chemical resistance, impact strength and tensile strength.

Abstract: Compositions formed from a blend of polyetherimide, siloxane/bisphenol-A polyester/polycarbonate copolymer, polycyclohexylenedimethylene terephthalate, polycarbonate/siloxane copolymer, and styrene-ethylene-butadiene-styrene are disclosed that provide superior performance in terms of notched Izod impact, glass transition temperature (Tg), strength after aging, ability to withstand secondary processing conditions, and in other respects. Such compositions exceed critical-to-quality requirements for use in manufacturing components for electronic communication devices.
