DEFINITION

Classification: 525/131

Contacting with -N=C=X-containing reactant and with additional organic reactant containing a hydroxyl or amine group:

(under subclass 123) Subject matter wherein the solid polymer from ethylenic reactants only is contacted both with a N=C=X-containing reactant and a OH or organic amine-containing reactant.

(1) Note. The contacting with the two necessary reactants can be concurrent or in any other manner.

SEE OR SEARCH THIS CLASS, SUBCLASS:

123, for a process involving contacting a solid polymer from ethylenic reactants only with a solid polymer which is the reaction product of a -N=C-X-containing reactant and a OH or -NH-containing reactant.
