  • Publication number: 20230174779
    Abstract: Disclosed are compositions comprising a) one or more polycarbonates; b) one or more first colorants; c) one or more flame retardants; and d) one or more particles having a melting point above the temperature at which polycarbonates are processed wherein the particles are coated with an organic polymer having a melting point above the processing temperature of the one or more polycarbonates; wherein the composition when molded exhibits a flecked appearance. The particles have a second colorant bound to the surface of the particles by the organic polymer. The organic polymer may be crosslinked. The one or more polycarbonates may comprise post-consumer recycled polycarbonates. Disclosed are molded products prepared from the disclosed compositions. The molded products exhibit good properties as disclosed herein. The molded products have a flecked appearance.

  • Patent number: 11208574
    Abstract: Articles comprising: a molded substrate comprising one or more polycarbonate resins or blends of polycarbonate and polyester resins containing polydimethyl siloxanes modified with one or more of acrylate, hydroxyl or epoxy groups and disposed on the surface or a portion of the surface of the substrate is a cured silicone rubber; wherein the one or more polycarbonate resins or blends of polycarbonate and polyester resins contain the modified polydimethyl siloxanes in sufficient amount such that the peel strength is increased. Compositions comprising one or more polycarbonate resins or blends of polycarbonate and polyester resins containing polydimethyl siloxanes modified with one or more of acrylate, hydroxyl or epoxy groups in an amount of about 0.1 to less than 1.0 percent by weight. Methods for preparing the articles are disclosed.
