1. A thermoplastic polyester/polycarbonate composition consisting essentially of:
a) 40 to 98 weight percent of a polymer blend based on the total weight of the polymer blend plus the impact modifier blend, said polymer blend consisting of:
1) 5 to 65 weight percent of one or more polyesters and/or polyamides based on the total weight of the polymer blend, said polyester selected from the group consisting of polyethylene terephthalate (PET), polybutylene terephthalate (PBT), polyethylene naphthalate (PEN) and mixtures thereof (ii); and2) 35 to 95 weight percent of polycarbonate based on the total weight of the polymer blend; b) 2 to 60 weight percent an impact modifier blend based on the total weight of the polymer blend plus the impact modifier blend, comprising
a. 1 to 50 weight percent of a core-shell copolymer based on the total weight of the impact modifier blend, said core-shell copolymer comprising an elastomeric core and having a particle size between 200 and 450 nm; andb. 50 to 99 weight percent of a functionalized polyolefin based on the total weight of the impact modifier blend, c) optionally from 0.25 to 30 weight percent, based on the total thermoplastic composition of one or more components selected from the group consisting of glass fiber, glass beads, organic filler, inorganic filler, talc, dyes, pigments, UV absorber, processing aids, carbon nanotubes, and carbon black, and d) inhibitor. |
