Abstract
The tensile strength and flexural strength of glass fiber reinforced aromatic polycarbonate resin/poly(butylene terephthalate) resin blends is improved by employing a glass fiber reinforcing agent treated with a sizing agent selected from epoxy functional cyanurates and isocyanurates. The reinforced blends are useful for making molded articles.
Claims6
A thermoplastic resin composition comprising:
- (a) an aromatic polycarbonate resin present at a level of from 4% to 49% by weight based on the total weight of said composition;
- (b) a poly(1,4 butyleneterephthalate) resin present at a level of from 50% to 95% by weight based on the total weight of said composition;
- and
- (c) a glass fiber reinforcing agent treated with a sizing agent selected from the group consisting of diepoxy functional cyanurates, triepoxy functional cyanurates, diepoxy functional isocyanurates, and triepoxy functional isocyanurates.
