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°C. The coating is formed to a thickness between about 0.1 and 0.6 mil.

A process for forming a gas-barrier coating on a film, sheet or foil, said coating being an aromatic polyamide, polyimide, polyamide-imide, polyhydrazide, polyamidehydrazide or polyazomethine formed by the direct vapor-phase condensation polymerization of their respective monomers, which process com
A process for forming a gas-barrier coating on a film, sheet or foil, said coating being an aromatic polyamide, polyimide, polyamide-imide, polyhydrazide, polyamidehydrazide or polyazomethine formed by the direct vapor-phase condensation polymerization of their respective monomers, which process comprises vaporizing said monomers, mixing said vaporized monomers in the presence of an inert diluent gas and reacting said mixed monomers in a reaction zone, in the presence of said film, sheet or foil maintained above the critical minimum deposition temperature of said monomers but below about 300°C., and forming the condensation polymer on the surface of said film to a thickness between about 0.01 and about 0.6 mil. A film, sheet or foil having a gas-barrier coating thereon of an aromatic polyamide, polyimide, polyamide-imide, polyhydrazide, polyamide-hydrazide or polyazomethine formed onto said film by the direct vapor-phase condensation polymerization of their respective monomers mixed in the vapor state and reacted in the presence of said film, sheet or foil maintained above the critical minimum deposition temperature of said monomers but below about 300°C., said coating having a thickness between about 0.01 and about 0.6 mil.
