Abstract
A uniaxially-stretched, high yield extruded capacitor film comprising a miscible polymer blend comprising a polyetherimide and a polyester, wherein the polyetherimide comprises units derived from polymerization of an aromatic dianhydride with a diamine comprising a m-phenylenediamine, a p-phenylenediamine, or combinations thereof, wherein the polyetherimide is endcapped with a substituted or unsubstituted aromatic primary monoamine, wherein the polyester comprises repeating structural units derived from polymerization of an aromatic dicarboxylic acid with a dihydroxy compound, and wherein the high yield extruded capacitor film comprises equal to or greater than about 90 wt. % of the miscible polymer blend entering an extruder used for manufacturing the capacitor film, based on the total weight of miscible polymer blend prior to entering the extruder.
