A process for subjecting a monomer to the action of ionizing radiation at an intensity greater than 0.1 Mr per minute to cause it to be polymerized when the monomer is in contact with a solid polymer is described The polymer liquid is added to the monomer to facilitate dissolution or swelling of the polymer. The desired dose es delivered by gradually treating the swollen polymer in the monomer wit a portion of the total desired dose Then the polymer is reswollen in the monomer and treated with a further dose until the desired dose is reached The polymers are polyethylene or cellulose The monomers are methyl methacrylate, methacrylic acid, vinyl acetate, acrylonitrile, or vinylidene chloride. The ionizing radiation is a beam of electrons from a Van de Graff generator. (N.W.R.)
