AbstractSynthetic‐polymer plates with carboxyl group on their surface were prepared by a two‐step copolymerization process transferring M2 monomer via vapor phase. Diethylene glycol bis(allyl carbonate) (CR‐39) was used as M1 monomer, and acrylic acid was acid was used as M2 monomer. The relations between the experimental conditions and the surface properties of the resulting plates were examined in the following terms: (1) composition of CR‐39 prepolymer gel plate used and (2) concentration of benzoyl peroxide as the initiator. The plates had good water wettability and an excellent antifogging property.
