Abstract:
A molded thermoplastic resin composition consisting essentially of:a) a polycarbonate, a rubbery impact modifier, anda polyester resin wherein the ratio of polycarbonate to polyester is greater than or equal to about 1.2, said polycarbonate resin being present at a level of from 40 to 85 percent by weight based on the total weight of the composition and said polyester is present at a level of from 5 to 45 percent by weight based on the total weight of said composition andb) non-bonding glass fibers present at a level of from 10 to 20 percent by weight based on the total weight of the composition, said glass fibers having been treated with a coating agent comprising a polyolefin wax, said rubbery impact modifier comprises methylacrylate-butadiene-styrene, acrylic or graft or core shell rubber impact modifier, said molded thermoplastic resin having a biaxial impact in ft-lbs equal to or greater than about 20.9 and an Unnotched Izod equal to or greater than about 30 wherein said properties are measured using ASTM tests D256 for Iod and ASTM test D3763 for biaxial impact.
