Abstract
Abstract Disclosed are epoxy-azido compounds of the formula ##EQU1## WHERE R is a polyvalent organic radical, R' is a hydrogen, alkyl, cycloalkyl, aryl, or aralkyl radical, A is ##EQU2## and n and m are integers from 1 to 100. Also disclosed is the use of said epoxy-azido compounds in modifying polymers, cross-linking polymers, and adhering polymers to certain substrates, e.g. glass and other polymers.

A process of cross-linking of polymer which comprises the steps of (1) modifying by heating a polymer selected from hydrocarbon polymers, cellulose esters, cellulose ethers, polyesters, poly(alkylene oxide) polymers, polyamides, allyl pentaerythritol derivatives, poly(vinyl alkyl ethers), poly(vinyl acetals), vinyl chloride polymers, nitrocellulose, chlorinated natural rubber, sulfochlorinated polyethylene, polysulfide rubber, polyurethane rubber, poly(vinyl acetate), ethylene--vinyl acetate copolymers, poly(vinylidene chloride), vinylidene chloride--acrylonitrile copolymers, ethyl acrylate--2-chloroethyl vinyl ether copolymers, poly(ethyl acrylate), poly(ethyl methacrylate), poly[3,3-bis(chloromethyl)oxetane], vinyl modified poly(dimethylsiloxane), polychloroprene, and butadiene--acrylonitrile copolymers in admixture with from about 0.1% to about 20% by weight of an epoxy-azido compound having the formula ##EQU5## where R is an organic radical selected from the group consisting of radicals derived by the removal of two or more hydrogen atoms from alkanes, cycloalkanes, alkylcycloalkanes, arenes, alkyl substituted arenes, alkylenediarylenes, dialkylcycloalkanes, alkyloxyalkanes, aryloxyarenes, alkaryloxyarenes, alkaryloxyalkarenes, aralkyloxyalkanes, aralkyloxyaralkanes, alkylthioalkanes, arylthioarenes, alkarylthioarenes, alkarylthiolkarenes, aralkylthioalkanes, aralkylthioaralkanes, alkylsulfonylalkanes, arylsulfonylarenes, alkarylsulfonylarenes, alkarylsulfonylalkarenes, aralkylsulfonylalkanes, aralkylsulfonylaralkanes, and the foregoing radicals with fluoro, chloro, bromo or iodo substituents, R' is a radical selected from the group consisting of hydrogen, alkyl, cycloalkyl, aryl, and aralkyl radicals, A is a radical selected from the group consisting of ##EQU6## and --SO 2 --and n and m are integers from 1 to 10 and (2) treating the thus modified polymer with an amount of polyfunctional agent sufficient to insolubilize the product, said polyfunctional agent being selected from the group consisting of polycarboxylic acids and polyamines.
