Abstract:
THE PRESENT INVENTION RELATES TO NOVEL PROCESSES BY WHICH SUBSTITUENT GROUPS AND CROSSLINKS CAN BE INTRODUCED INTO CELLULOSE AND OTHER POLYMERIC COMPOSITIONS CONTAINING REACTIVE HYDROXYL GROUPS. THE NOVEL PROCESSES OF THIS INVENTION AND THE NOVEL PRODUCT OF THIS INVENTION ARE BASED ON THE DISCOVERY THAT QUATERNARY AMMONIUM AND TERTIARY AMINO HYDROXIDE GROUPS DEVELOPED AS SUBSTITUENTS IN POLYMERIC COMPOSITIONS, CATALYZE THE EACTION OF ACTIVATED VINYL COMPOUNDS WITH THE HYDROXYL GROUPS OF THESE POLYMERS.
