Abstract: A nano-composite includes a thermoplastic copolymer includes a polycarbonate copolymer including repeating siloxane units and a plurality of quantum dots. A method of making a polymer film includes forming a masterbatch composition by combining (1) a first thermoplastic copolymer including a polycarbonate copolymer including repeating siloxane units and (2) a plurality of quantum dots; combining the masterbatch composition with a second thermoplastic polymer to form a mixture; and forming the polymer film from the mixture. The polycarbonate copolymer has a siloxane content of from 15 wt % to 65 wt %.

Abstract: Thermoplastic compositions include: (a) from about 30 wt % to about 95 wt % poly(methyl methacrylate) (PMMA); and (b) 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 %. Methods for making a molded article, include: (a) combining from about 30 wt % to about 95 wt % 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 blend; (b) melt processing and pelletizing the blend; and (c) injection molding the article from the melt processed and pelletized blend.

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.
