19 Claims

1. A polymer composition comprising:

from about 40 wt. % to about 80 wt. % of a polyetherimide resin;

from about 1 wt. % to about 40 wt % of a crystalline polyester resin;

from about 15 wt. % to about 45 wt. % of an inherently dissipative polymer; and

from about 0.001 wt. % to about 10 wt. % of a transesterification inhibitor,

wherein the polymer composition exhibits a surface resistivity of from 1×10⁹ohms to 9×10¹⁰ohms when measured in accordance with ASTM D257 and a volume resistivity of from 1×10⁸to 9×10⁹ohms cm in accordance with ASTM D257, and

wherein the combined weight percent value of all components does not exceed about 100 wt. %, and all weight percent values are based on the total weight of the polymer composition.
