摘要
A modified polyvinyl alcohol and a solid state process for producing modified polyvinyl alcohol wherein polyvinyl alcohol powder is sprayed with a sufficient amount of a solution of a polymerizable monomer to swell the polyvinyl alcohol powder but not dissolve it or form a slurry. The swollen polyvinyl alcohol powder is sprayed with a free radical source (an initiator) and the temperature is raised to initiate a reaction between polyvinyl alcohol and the polymerizable monomer.
