Abstract
Process for, and composites made by, coating a polymer layer onto a support, obtained by quenching a solution of the polymer to form a polymer suspension, by spreading the suspension on the support, and thereafter eliminating the solvent. The resulting coating of polymer preferably may thereafter be fused. Application of said process to the production also composites comprising an aluminum film and a film thermally bonded to said support by a thin intermediate layer of a copolymer formed of acrylic acid grafted with polyethylene or polypropylene, said layer having been applied by the foregoing process.
