Zusammenfassung:	A polymer composition including a polyetherimide comprising repeating units of formula (1) and formula (2) [Formula should be inserted here] wherein the repeating units of formula (1) are present in an amount of at least 10 mole %, preferably 20 to 100 mole %, Z is independently at each occurrence derived from a biphenol; Z' is independently at each occurrence a group of formulas (3) to (13) as defined herein, preferably bisphenol A, 1,2-dihydroxybenzene, 1,1-bis(4-hydroxyphenyl)-1-phenyl-ethane, isophorone bisphenol (1,1-bis(4-hydroxyphenyl)-3,3,5-trimethylcyclohexane), spirobiindane bisphenol, dimethylindanone bisphenol, 3,3'-dimethylbisphenol cyclohexane, or fluorenone bisphenol; and R is independently at each occurrence as a C6-20 aromatic hydrocarbon group or a halogenated derivative thereof, a straight or branched chain C2-20 alkylene group or a halogenated derivative thereof, a C3-8 cycloalkylene group or halogenated derivative thereof; wherein the polyetherimide has a Tg of greater than 200°C.
