Abstract
PURPOSE:To obtain a reverse permeative complex film excellent in selective permeability, chemical resistance, heat resistance and the like by bridging the film of a polymer containing a specific polyaminostyrene structural unit thru a microporous support film with a specific compound. CONSTITUTION:A polymer containing a polyaminostyrene structural unit represented by the formula I, where R<1> represents a substituent having in a molecule 7 or less carbon atoms; R<2>, hydrogen atoms or ethyl group; R<3>, an aromatic amino group or the like; and m, an integer of 1 through 3; n, 0 or 1 through 3; and m+n<=4, in a quantity of 30% or more of the total repetitive unit, is solved in 0.1-100g/l of water, or an organic polar substance. Thereto added are aldehydes, methylol compounds and reactive derivatives thereof, which react with the groups of the polymer represented by the formula II in two functional groups. The thus prepared film is applied to or impregnated in a microporous support film, and subjected to a heat treatment and bridged, or after the polymer solution is applied on the support film, it is brought into contact with the compound to carry out the bridging.
