Method for making aqueous emulsions of functionalized organic polymers

摘要

There is claimed herein an aqueous emulsion comprising a functionalized organic polymer formed by mixing (a) a preformed aqueous emulsion comprising water, particles containing a plurality of silanol modified organic polymer molecules dispersed in the water, and a surfactant; (b) a functionalizing silane and (c) a tin catalyst. Depending on reaction conditions, these emulsions are predominantly non-precrosslinked and photocurable compositions that are crosslinked after application in either the wet or dry state.
