Polymeric materials having controlled physical properties and processes for obtaining these

Abstract From the Canadian patent

Ground polymeric elastomer or other polymeric plastic particularly, from recovered scrap, is surface modified by treatment with a gaseous mixture containing a minor amount of fluorine and a larger amount of at least one reactive gas in an inert gaseous carrier. By the treatment the ground material is made more compatible for admixture with polyfunctional polymer-forming liquids, thereby obtaining novel composites of controlled physical properties. The other reactive gas is preferably oxygen or one of the gases from the group consisting of: chlorine and SO2 with or without added oxygen.
