  • Polycarbonate composition and articles formed therefrom
    Patent number: 9169395
    Abstract: A composition includes at least one poly(aliphatic ester)-polycarbonate copolymer, a polysiloxane-polycarbonate copolymer, and an electromagnetic shielding agent (such as metal fibers). The composition exhibits excellent impact properties and electromagnetic shielding properties when formed into an article. Another composition includes at least one poly(aliphatic ester)-polycarbonate copolymer, a polysiloxane-polycarbonate copolymer, and carbon fibers. This composition has excellent impact properties when formed into an article.
    Type: Grant

  • Process for preparing a fire resistant polycarbonate composition
    Patent number: 7390450
    Abstract: A process for producing a fire resistant polycarbonate composition comprises preparing an aqueous solution of a flame retardant salt; and compounding the aqueous solution of the flame retardant salt with a polycarbonate composition to form the fire resistant polycarbonate composition. The process reduces the level of haze, color and inclusions compared to fire resistant polycarbonate compositions compounded with the same flame retardant salt in solid form.
    Type: Grant

  • Method of branching and cross-linking a polycarbonate resin
    Patent number: 6087468
    Abstract: The disclosure describes reacting a multi-functional phenolic or carboxylic branching agent with a transesterification catalyst to form an organic salt prior to reactive extrusion of said organic salt branching agent with linear polycarbonate resin as a means to dramatically increase the efficiency of the branching agent in the preparation of branched polycarbonate.
