Sulfonamide polymer matrices and their various uses are disclosed. Among the uses is the configuration of the matrix with a porous support membrane to form a semipermeable membrane of the invention. The matrix of the invention is ultrathin, dense and substantially free of defects. The matrix configuration as the semipermeable membrane shows improved permeate flux and retention values.
L'invention concerne des matrices polymères sulfonamides et leurs multiples utilisations. Un mode de réalisation décrit dans cette invention concerne une configuration de matrice présentant une membrane de support poreuse, permettant ainsi de former une membrane semi-perméable. La matrice décrite dans cette invention est ultraplate, dense et sensiblement exempte de défauts. La configuration de membrane semi-perméable présente des valeurs améliorées de rétention et de débit de perméation.
