Publication date: 2000
Publication number: JP2000342943

Abstract: PROBLEM TO BE SOLVED: To provide an optical splitting nylon film capable of selectively separating an optical activator economically by a simple method and a method for producing the same. SOLUTION: A nylon film has a glass transition temp. of 70 deg.C or higher and has optically active function molecularly imprinted by a D- and/or L-optical activator and is produced by bringing a film obtained from a blend of 100 pts.wt. of nylon with a glass transition temp. of 70 deg.C or higher and 1-200 pts.wt. of the D- and/or L-optical activator into contact with a solvent not dissolving nylon but dissolving the optical activator to remove the D- and/or L-optical activator from the nylon film.
