ABSTRACT:
A thermosetting resin designated a "APT" resin is produced by a two-step procedure in which a substituted aromatic compound, preferably diphenyl ether is reacted with formaldehyde to produce an oligomeric backbone, followed by further reaction with a phenol to provide pendant phenolic groups. Finally, the resulting polymer is cyanated with a cyanogen halide.
