Abstract
Continuous polymer film of the polyacenequinone radical (PAQR) type, substrates coated with PAQR, and the method of coating a PAQR film comprising insister polymerization of at least on aromatic acene hydrocarbon monomer and at least one acidic monomer selected from di- or tri-aromatic anhydrides or derivatives thereof on a substrate by heating deposited monomers slowly under oxygen excluding conditions to a temperature of at least 300.degree. C. and post-curing the formed film at a temperature above 300.degree. C. thus forming a continuous, integral, pin-hole-free PAQR film on the substrate.
