Abstract
Disclosed are epoxy-azido compounds of the formula ##EQU1## or --SO.sub.2 -- where R is a polyvalent organic radical, R' is a hydrogen, alkyl, cycloalkyl, aryl, or aralkyl radical, A is And n and m are integers from 1 to 100. Also disclosed is the use of said epoxy-azido compounds in modifying polymers, crosslinking polymers, and adhering polymers to certain substrates, e.g. glass and other polymers.
