Abstract
Abstract Epihalohydrin polymers can be cross-linked by reaction with a poly(diazoacetate) having the general formula WHERE X IS AN INTEGER GREATER THAN 1 AND R is an organic radical inert to modification reactions. The reaction between the poly(diazoacetate) and polymer can be initiated either by heating or by exposing to ultraviolet radiation.
