MODIFICATION OF ETHYLENICALLY UNSATURATED POLYMERS WITH POLYFUNCTIONAL QUATERNARY AMIDOXIMIDINIUM SALTS

摘要

The invention relates to the modification of ethylenically unsaturated polymers using polyfunctional quaternary amidoximidinium salts as the modifying agents. These salts are precursors to the corresponding polyfunctional nitrile N-oxides and the latter, upon being generated from the salt precursors, are the active modifying agents in the modification process. Representative of these salts is terephthalo-bis(hydroximoyl pyridinium chloride).
