DEFINITION

Classification: 525/126

Contacting solid polymer from ethylenic reactants only with ethylenic reactant wherein said contacting is either concurrent with or subsequent to contacting of said solid polymer with the -N=C=X reactant or polymer thereof:

(under subclass 123) Subject matter wherein a solid polymer from ethylenic reactants only is contacted with an ethylenic which is devoid of any -N=C=X group and wherein said contacting is either concurrent with or subsequent to the contacting of the solid polymer with the -N=C=X containing reactant; or wherein the solid polymerized ethylenic reactant is contacted simultaneously with an unsaturated-N=C=X-containing reactant and with a saturated coreactant and wherein the-N=C=X reactant and the saturated coreactant are necessary ingredients of a specified polymer-forming ingredient system.
