✦ Synopsis

A new preparation technique of the polymer plate with high water wettability and sufficient mar resistance was proposed. The gel plate resulting from the prepolymerization of diallyl compound ( M I ) , diallyl phthalate (DAP), in a casting cell was immersed in an aqueous solution of unsaturated carboxylic acid ( M z ) , acrylic acid (AA), and methacrylic acid (MAA), at a specific temperature for a specific time. M z was copolymerized with the remaining M I in the region near the surface of the gel plate, and polymer plates with the following characteristics were obtained: for DAP-AA system, Bi (contact angle of the alkali-treated plate) = 10.5' and mar resistance (for the alkali-treated plate at a dry state) = 70 g; for DAP-MAA system, Bi = 8.3', and mar resistance = 65 g.

## Abstract Polymer plates with high surface energy were prepared by the procedure described in the previous paper, using diethylene glycol bis(allyl carbonate) as a substrate polymer and acrylic acid or methacrylic acid as a hydrophilic monomer. By the alkali treatment (immersing in an aqueous 0.1
