Abstract: A process for making a blended composition includes: i) obtaining (A) a recycled polypropylene composition from a waste plastic material, ii) melt-mixing (A) with (B) a heterophasic propylene copolymer and (C) an inorganic filler, wherein (B) consists of (al) a propylene-based matrix consisting of a propylene homopolymer/copolymer consisting of at least 90 wt % of propylene monomer units and at most 10 wt % of ethylene and/or α-olefin monomer units, and (a2) a dispersed ethylene-α-olefin copolymer, copolymer (B) has a xylene soluble content of 12 to 27 wt %, an MRI at 230° C./2.16 kg of 5.6 to 65 dg/min, wherein the recycled composition includes at least 90 wt % a propylene-based polymer, has an ash content of less than 10 wt %, an MFI at 230° C./2.16 kg of 15 to 100 dg/min, an Izod impact strength (23° C.) of 2.0 to 5.0 kJ/m2, and a flexural modulus (23° C.) of 1500 to 2000 MPa.

Abstract: A polycarbonate composition comprises: 30 to 95 wt % of one or more bisphenol A polycarbonate homopolymers; and 5 to 70 wt % of a poly(carbonate-siloxane) copolymer with a siloxane content of 10 wt. % to 25 wt. % based on the total weight of the poly(carbonate-siloxane), in an amount effective to provide a total siloxane content of 0.5 wt. % to 17.5 wt. % based on the total weight of the composition; the poly(carbonate-siloxane) copolymer comprising bisphenol carbonate units and siloxane units of the formulas or a combination comprising at least one of the foregoing, wherein E has an average value of 10 to 100, preferably 20 to 60, more preferably 30 to 50; wherein in the poly(carbonate-siloxane) copolymer less than 0.5 mol % of the siloxane units are directly coupled to another siloxane units.
