POLYMERIC MATERIALS HAVING CONTROLLED PHYSICAL PROPERTIES AND PROCESSES FOR OBTAINING THESE |
摘要 |
<p>Ground polymer 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.</p> |
