Abstract
A poly(etherimide) includes repeating units derived from polymerization of a biphenol dianhydride and an organic diamine. A method of making the poly(etherimide) includes contacting the biphenol dianhydride and the organic diamine under conditions effective to provide a poly(etherimide). The poly(etherimide) can be useful in a variety of articles, for example in an optoelectronic component.
