| abstract | PURPOSE: To improve the water absorption properties by applying an aqueous solution containing a specific polymer which contains unsaturated groups on a substrate, and irradiating it with actinic radiation to crosslink. n CONSTITUTION: 0.1-2wt.% monoepoxidized unsaturated compound (e.g. glycidyl acrylate) is added to an aqueous solution which contains 5-10wt.% carboxylated polymer (e.g. polysodium acrylate) and the mixture is heated at 60-80°C for 2-4hr, thereby allowing the carboxylate group and the epoxy group to undergo an esterification reaction to produce an aqueous solution which contains an unsaturated polymer. Then, if desired, 0.1-5wt.% photopolymerization initiator (e.g. benzoin methyl ether) and a photosensitizer (e.g. trimethylamine) are added to this aqueous solution and the mixture is applied on a fibrous porous sheet substrate and is predried, thereby forming a film which has a water content of 10-30wt.%. Actinic radiation is applied to the film within 1min to form crosslinks in the polymer. n COPYRIGHT: (C)1991,JPO&Japio |
