Abstract:
A process for the insolubilization of N-(vinyl)phenylacrylamide polymers which comprises polymerizing or copolymerizing by cationic catalysts thereby producing soluble polymers, and irradiating the resulting soluble polymers with light in the presence of a light polymerization initiator thereby polymerizing the vinyl groups remaining in said soluble polymers and threedimentional network structure polymers produced by the above mentioned process.
