- 2. A resinous composition comprising
a) at least one aromatic polycarbonate, b1) about between 0 wt % and about 35 wt % of a second thermoplastic resin comprising structural units derived from one or more monomers selected from the group consisting of vinyl aromatic monomers, monoethylenically unsaturated nitrile monomers, and C1-C12 alkyl (meth)acrylate monomers, b2) about between 0 wt % and about 35 wt % of one rubber modified graft copolymer comprising a discontinuous rubber phase dispersed in a continuous rigid thermoplastic phase, wherein at least a portion of the rigid thermoplastic phase is chemically grafted to the rubber phase, c) about 1 to 10 wt. % of at least one low molecular weight hydrocarbon resin derived from petroleum C5-C9 feedstock; wherein all amounts are based on the sum of the weights of components a-c inclusive of the composition.
- 3. The composition of claim 1 wherein the low molecular weight hydrocarbon resin derived from petroleum C5-C9 feedstock has a numbered average molecular weight of less than 5,000, preferably less than 2,500.
- 4. The composition of claim 1 wherein the low molecular weight hydrocarbon resin derived from petroleum C5-C9 feedstock is partially or fully hydrogenated.
- 5. The composition of claim 1 wherein the low molecular weight hydrocarbon resin derived from petroleum C5-C9 feedstock is a partially or fully hydrogenated Cg resin.
- 6. The composition of claim 1 further comprising about 0.5 wt % and about 15 wt %, based on the weight of the components a-d of the composition, of at least one polymeric or non-polymeric organic phosphorus species selected from the group consisting of aromatic or non-aromatic phosphate esters, thiophosphate esters, phosphonate esters, thiophosphonate esters, phosphinate esters, thiophosphinate esters, phosphines, triphenylphosphine, phosphine oxides, triphenylphosphine oxide, tris(2-cyanoethyl)phosphine oxide, thiophosphine oxides, and phosphonium salts.
- 7. The composition of claim 1, comprising as polycarbonate a blend of a first polycarbonate not comprising siloxane units and as a second polycarbonate a linear multiblock copolymer of bisphenol A polycarbonate and polydimethylsiloxane.
- 8. The composition of claim 1, wherein the second thermoplastic resin comprises structural units derived from styrene and acrylonitrile; and the rubber modified graft copolymer rubber phase comprises a polybutadiene or poly (styrene-butadiene) rubber and the rigid thermoplastic phase comprises a styrene-acrylonitrile copolymer.
- 9. An article fabricated from the composition of claim 1.
- 10. A method for making a thermoplastic resin composition comprising blending:
a) at least one aromatic polycarbonate, b) about between 0 wt % and about 50 wt % of a second thermoplastic resin which is not a polycarbonate, c) about 1 to 10 wt. % of at least one low molecular weight hydrocarbon resin derived from petroleum C5-C9 feedstock, wherein all amounts are based on the weight of components a-c inclusive of the composition.
