ABSTRACT:
A solid state process for modifying polyvinyl alcohol using a Michael-type addition wherein dry polyvinyl alcohol powder is sprayed with a solution of a monomer capable of Michael-type addition in an amount sufficient to swell the polyvinyl alcohol or maintain its swollen state, but not dissolve or form a slurry of the polyvinyl alcohol. The swollen polyvinyl alcohol is sprayed with a catalyst and the temperature is raised to initiate the reaction between the polyvinyl alcohol and the monomer.
