Abstract: A thermoplastic composition includes: a first branched polycarbonate copolymer end-capped with 4-hydroxybenzonitrile (4-HBN) having a molecular weight M1; and a second branched polycarbonate copolymer end-capped with 4-HBN having a molecular weight M2. M1 is less than M2. Methods for determining entanglement molecular weight (Me) of a polycarbonate copolymer include: preparing a sample of a branched polycarbonate copolymer including a 1,1,1-tris-hydroxy-phenylethane (THPE) branching agent and that is end-capped with 4-HBN; determining phase angle (∂) versus complex modulus (G*) of the sample using a small amplitude oscillatory rheology process at a specified temperature; determining a minima in the ∂ of the sample; determining a plateau modulus (GN) of the sample from the determined minima of ∂; and calculating the Me of the sample from the GN.

Abstract: Provided is a silane-crosslinkable polyolefin-based flame-retardant resin composition having high flexibility and high handleability, and an insulated electric wire and a wire harness obtained using the flame-retardant resin composition. The flame-retardant resin composition includes, as resin components: a silane-grafted polyolefin (A) obtained by grafting a silane coupling agent onto a polyolefin; an unmodified polyolefin (B); and a modified polyolefin (C) having one or more functional groups selected from a carboxyl group, an ester group, an acid anhydride group, an amino group, and an epoxy group. The resin composition further includes a flame retardant (D) and a crosslinking catalyst (E). A crosslinked product obtained by subjecting the flame-retardant resin composition to silane crosslinking has a melting point of 80° C. or higher and a flexural modulus of 100 MPa or less.

Abstract: A composition having flame retardant properties comprising a polymeric material and a bauxite as flame retardant filler dispersed in the polymeric material, wherein the bauxite has an aluminum hydroxide content of at least 50% by weight and is in the form of particles having an average size (d50) not higher than 8.0 μm and a specific surface area (BET) not higher than 10.0 m2/g. These compositions provide excellent performance in terms of both self-extinguishing and mechanical properties, in particular elongation at break. Such compositions may be used to produce cable jackets for the transport or distribution of electrical energy and/or for telecommunications, panels and coverings for buildings, pipes, and the like.
