ABSTRACT:
Step-growth polymers can be prepared by reacting a mixture of diphenylether or di(phenoxyphenyl)sulfone with biphenylene and a phthaloyl halide in the presence of a Friedel-Crafts acylating catalyst. These polymers can be cured by heating in the range 300.degree.-340.degree. C., with cross-linking occurring by reaction of formed biphenylene diradicals.
