Abstract
Thermostable, infusible and insoluble polymer obtained by thermosetting aromatic oligomers of low molecular weight in the presence of an acid catalyst, said aromatic oligomers having an average molecular weight up to about 5000, a softening temperature from 80.degree. to 400.degree. C. and being obtained by separation from the reaction mixture produced by reacting meta-terphenyl with acetyl chloride and aluminum chloride.
