Patent ID: 8293831

Claim:
A thermoplastic composition comprising: a) from about 10 to about 79.9 wt % of at least one semi-aromatic polyamide having a glass transition equal to or greater than 100° C. and a melting point of equal to or greater than 280° C., as determined with differential scanning calorimetry at a scan rate of 20° C./min; b) from about 20 to about 80 wt % of a thermally conducting filler having a thermal conductivity of at least 5 W/mK; and c) from about 0.1 to about 10 wt % of at least one hyperbranched polyesteramide having terminal hydroxyl groups; and wherein said at least one semi-aromatic polyamide is selected from the group consisting of poly(decamethylene terephthalamide), poly(nonamethylene terephthalamide), hexamethylene terephthalamide/2-methylpentamethylene terephthalamide copolyamide; hexamethylene adipamide/hexamethylene terephthalamide/hexamethylene isophthalamide copolyamide; poly(caprolactam/hexamethylene terephthalamide); and hexamethylene terephthalamide/hexamethylene isophthalamide copolymer.
