Abstract: A thermoplastic composition includes from about 30 wt % to about 95 wt % poly(methyl methacrylate) (PMMA), and from about 5 wt % to about 70 wt % of a poly(carbonate-siloxane) copolymer having a siloxane content of from about 25 wt % to about 45 wt %. A method of making a thermoplastic composition includes: (a) combining from about 30 wt % to about 95 wt % poly(methyl methacrylate) (PMMA) and from about 5 wt % to about 70 wt % of a poly(carbonate-siloxane) copolymer having a siloxane content of from about 25 wt % to about 45 wt % to form a mixture; and melt processing the mixture to polymerize it and form the thermoplastic composition.

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: An article includes at least two contiguous layers containing a composition that includes a branched polycarbonate, optionally a linear carbonate-containing polymer, and 0 to less than 5 weight percent filler. The composition is characterized by an average mole percent branching of 0.06 to 2.4 mole percent, which is calculated as 100 times moles of branched carbonate units in the branched polycarbonate divided by the sum of moles of linear carbonate units in the branched polycarbonate and the optional linear carbonate-containing polymer. The composition is further characterized by a melt flow rate of 1 to 20 grams per 10 minutes, determined according to ASTM D1238-13 at 300° C. and 1.2 kilogram load. Also described is a method of additive manufacturing utilizing the composition.
