  • Publication number: 20230391977
    Abstract: Toughened thermoplastic polymers having elastomeric domains in thermoplastic polymer may be recycled by a method comprising dissolving the thermoplastic polymer in a solvent to form a solution, wherein the elastomer is dispersed within the solution as elastomer particulates or droplets, applying a sufficient centrifugal force to the solution to separate the elastomeric particulates or droplets from the solution to form a separated system and (c) recovering the thermoplastic polymer and elastomeric polymer by removing one or both from the separated system. The recovered elastomer and thermoplastic polymer may then be reused in the same type, similar or differing plastics avoiding degradation typically found when recycling toughened thermoplastic polymers.

  • Publication number: 20200353726
    Abstract: Disclosed are laminate composition comprising one or more layers of a fiber structure and two or more layers of a polymeric composition wherein each layer of the fiber structure is disposed between two layers of the polymeric composition wherein the polymeric composition comprises one or more branched polycarbonates and one or more crosslinked phosphazenes; wherein the laminate composition exhibits a UL 94 rating of V-0 with a ? (T1-T2) of 50 or less. The polymeric film composition may contain one or more linear polycarbonates. The polymeric film composition may contain one or more recycled branched polycarbonates or one or more recycled linear polycarbonates. The polymeric film composition may contain one or more salts of a perflourohydrocarbyl sulfur N compounds or aromatic sulfur compounds.
