Abstract
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.
