Abstract
PURPOSE: To improve a shape atability, a film strength, and film-making qualities, by a method wherein a film is made by the use of a blended matter or a copolymer of a cellulosic polymer soluble in an organic solvent and a polymer having a tertiary amino group in the side chain of the polymer.
CONSTITUTION: An oxygen selective permeable film is made after a mixture or a copolymer of a cellulosic polymer soluble in an organic solvent (polymer A) with a polymer having a tertiary amino group in the polymer side chain is dissolved in the common solvent therefor. Nitrocellulose, diacetylcellulose and the like are preferred as the polymer A, and poly-N, N-diethylaminoethyl acrylate and the like are preferred as the polymer B. The film made from the mixture of the polymer A and the polymer B is obtd. by dissolving the mixture in a common solvent thereof, and applying the resultant dissolution on a porous material or glass plate and removing the solvent.
