DEFINITION

Classification: 525/125

Contacting two or more solid polymers derived from ethylenic reactants only with a -N=C=X Reactant or polymer thereof; or contacting a polymer derived from an ethylenic reactant only with a -N=C=X reactant or polymer thereof and subsequently adding thereto a solid polymer derived only from ethylenic reactants:

(under subclass 123) Subject matter wherein two or more solid polymers derived from ethylenic reactants only are contacted with a -N=C=X-containing reactant or polymer derived therefrom; or contacting a solid polymer derived from ethylenic reactant only with a -N=C=X-containing reactant or polymers therefrom and subsequently contacting with an additional solid polymer from ethylenic reactants only.
