Production of films from carboxylic acid containing conjugated diene polymer and an amine containing conjugated diene polymer

Claim 1

A PROCESS FOR PRODUCING A POLYMERIC FILM WHICH COMPRISES BRINGING TOGETHER IN SEPARATE THIN LAYERS (A) 1 TO 99 PARTS BY WEIGHT, BASED ON TOTAL WEIGHT OF POLYMERIC MATERIALS, OF A FIRST POLYMERIC MATERIAL PREPARED BY COPOLYMERIZING A CARBOXYLIC ACID CONTAINING A POLYMERIZABLE ETHYLENIC UNSATURATION WITH 10-90 WEIGHT PERCENT OF A CONJUGATED DIENE OF 4 TO 8 CARBON ATOMS, SAID FIRST POLYMERIC MATERIAL BEING IN SOLUTION IN AN INERT SOLVENT, AND (B) 99 TO 1 WEIGHT PARTS OF A SECOND POLYMERIC MATERIAL PREPARED BY COPOLYMERIZING AN AMINE CONTAINING A VINYLIDENE GROUP ATTACHED TO A CARBON ATOM WITH 10-90 WEIGHT PERCENT OF A CONJUGATED DIENE OF 4 TO 8 CARBON ATOMS, SAID AMINE BEING SELECTED FROM THE GROUP CONSISTING OF PRIMARY, SECONDARY AND TERTIARY AMINES, SAID SECOND POLYMERIC MATERIAL BEING IN SOLUTION IN A SOLVENT AND EVAPORATING THE SOLVENTS THEREBY EFFECTING THE FORMATION OF SAID FILM.
