ABSTRACT:
Films, sheets or foils are given a gas-barrier coating of an aromatic polyamide, polyimide, polyamide-imide, polyhydrazide, polyamide-hydrazide, or polyazomethine by direct vapor-phase condensation polymerization of their respective monomers. The monomers are introduced in an inert diluent gas, mixed and reacted in the presence of the surface to be coated. The surface is maintained above the critical minimum deposition temperature of the monomers but below about 300.degree. C. The coating is formed to a thickness between about 0.1 and 0.6 mil.
