| titleOfInvention | Polycarbonate/polyester blends with improved thermal melt stability |
| abstract | Impact modified polycarbonate/polyester blends have improved thermal melt stability when containing a low-ion polymeric impact modifier. The low-ion polymeric impact modifier contains 5-80 percent rubber by weight, and is characterized by having a thermal-melt-stabilizing ion content, which (i) in a polymeric impact modifier containing more than 1.0 up to 5.0 wt. percent anti-oxidant, (A) is an ion content of sodium and potassium ions of not more than 1,500 ppm, and (B) is an ion content of all ions of not more than 1,700 ppm; and (ii) in a polymeric impact modifier containing 0.1 to 1.0 wt. percent anti-oxidant, (A) is an ion content of sodium and potassium ions of not more than 800 ppm, and (B) is an ion content of all ions of not more than 1,500 ppm. Reducing the ion content of a polymeric impact modifier in a polycarbonate composition reduces the degradative effect of ionic species on the composition at high temperature. |
