| titleOfInvention | PROCEDURE FOR THE PREPARATION OF MEMBRANES AND FILMS FOR REVERSE OSMOSIS. |
| abstract | Procedure for the preparation of membranes and films for reverse osmosis, characterized by forming a molding solution containing 0.5 to 25% by weight of a polymeric material of polyamide structure with iterative units of the general formula ** (See formula) ** in which the group -CO- CR'= CR''- CO - is in a trans configuration; R'and R'', the same or different from each other, are hydrogen, alkyl, cycloalkyl, aryl or halogen; n is an integer valued from 0 to 8; and R is a substituent group such as alkyl, cycloalkyl, aryl, alkoxy, aryloxy or halogen, substituent groups which are located according to any steric configuration, in a solvent for said solution, on a smooth surface, to form a thin and uniform membrane layer, dry said membrane at about 10 to 180ºC and remove the dry membrane from said smooth surface.
