Abstract
Abstract Mixtures of materials including solutions, gaseous mixtures, and colloids are purified or separated by contact with or passing through ion exchange or permselective materials which have been modified by polymer deposition or graft polymerization. The materials used in the separatory process are generally webs, membranes, beads, granules, or other shaped objects which have ion exchange capacity or permselective surface characteristics, which materials have been modified by graft polymerization or polymer deposition to provide the desired permselective or ion exchange characteristics.

Claims Analysis
Total Claims: 2
Claim 1
Independent Claim
127 words
A METHOD OF DYEING A POLYMERIC MATERIAL IN THE FORM OF A FIBER, FILM, WEB, OR FABRIC WHICH COMPRISES CHEMICALLY FIXING IN A PRESELECTED PATTERN, LESS THAN THE ENTIRE SURFACE THEREOF, A MATERIAL ADAPTED TO PROVIDE AT LEAST A PART OF A CATALYST FOR EFFECTING POLYMERIZATION OF AN OLEFINICALLY UNSATURATED MONOMER, WITHIN THE POLYMERIC MATERIAL BY ION EXCHANGE REACTION, TREATING THE POLYMERIC MATERIAL AND CHEMICALLY FIXED MATERIAL, IN ANY ORDER, WITH SAID OLEFINICALLY UNSATURATED MONOMER, AND ANYTHING ADDITIONAL REQUIRED TO RENDER SAID CHEMICALLY FIXED MATERIAL CATALYTICALLY ACTIVE, TO POLYMERIZE SAID MONOMER AND DEPOSIT THE RESULTING GUEST POLYMER WITHIN SAID POLYMERIC MATERIAL IN SAID PRESELECTED PATTERN, AND CONTACTING THE POLYMERI-MODIFIED MATERIAL WITH A DYE FOR THE GUEST POLYMER, WHEREBY SAID POLYMERIC MATERIAL IS DYED IN SAID PRESELECTED MATERIAL.
