Abstract

1,175,046. Treating polymer film. NIPPON KAKOH SEISHI K.K. 22 Nov., 1966 [27 Nov., 1965], No. 52728/66. Heading B5B. [Also in Division B6] Polymer film is made opaque to provide a paper-like surface by forming a swollen layer on its surface by treating it with a solvent or swelling agent for a sufficient period of time such that the surface layer is swollen but not dissolved therein and then coagulating the swollen layer by the action of a coagulating agent which is miscible with the treating agent but has no dissolving or swelling effect on the film and then drying the film. Mixtures of solvents and swelling agents and mixtures of coagulating agents may be used as may a mixture of a solvent or swelling agent and a coagulating agent to produce the swollen layer. Specified polymers are polyolefines, polyamides, polyurethanes, rubber derivatives and cellulose derivatives, vinyl chloride polymers, polystyrene and polymethyl methacrylate.
