Abstract

A process is described for the production of phosphorus-containing organic polymers through reaction of dialkyl phosphites with organic polymers comprising carbon-carbon double bonds in the presence of organic compounds that form free radicals under the reaction conditions, with covalent linkage of the phosphorus atom of the dialkyl phosphite to a carbon atom of the organic polymer.
