Patent ID: 7855001

Claim:
A thermoplastic polymer composition which is comprised of (1) a polyethylene terephthalate glycol copolyester, (2) from 1 weight percent to 6 weight percent carbon nanotubes, (3) from 2 weight percent to 30 weight percent of a copolymer of ethylene with a higher α-olefin, wherein the copolymer is of ethylene with the higher α-olefin is grafted with maleic anhydride or glycidyl methacrylate, (4) from 1 weight percent to 10 weight percent of a functionalized rubbery polymer, (5) from 1 weight percent to 10 weight percent of an acrylic based core-shell polymer, and (6) from 0.5 weight percent to 6 weight percent of a lubricant selected from the group consisting of high density polyethylene and polyester wax, where the polyethylene terephthalate glycol copolyester makes up the balance of the composition and wherein all weight percentages are based upon the total weight of the thermoplastic polymer composition.
