Polyester/polycarbonate blends with reduced yellowness |
摘要 |
Thermoplastic compositions of polyester/polycarbonate blends have reduced yellowness and improved thermal and melt stability when the polyester is produced with a reduced level of a titanium-containing catalyst in an amount of from about 1 to about 30 ppm elemental titanium, with ppm based on the total weight of the polyester.
