発明の名称 (英語) HYDROGEL OF (SEMI)INTERPENETRATING NETWORK STRUCTURE AND PROCESS FOR PRODUCING THE SAME
発明の概要(英語) A hydrogel of the semi-interpenetrating network structure or interpenetrating network structure, characterized in that the hydrogel is one formed from a first monomer ingredient at least 10 mol0f which is accounted for by a charge-possessing unsaturated monomer and a second monomer ingredient at least 60 mol0f which is accounted for an electrically neutral, unsaturated monomer, the molar ratio of the first monomer ingredient to the second monomer ingredient being from 1/2 to 1/100, and that the second monomer ingredient has been polymerized and crosslinked to a lower degree of crosslinking than the first monomer ingredient. The hydrogel is usable in a diaper, sanitary good, sustained-release agent, construction material, building material, communication material, soil conditioner, contact lens, ocular lens, hollow fiber, artificial cartilage, artificial organ, material for fuel cells, battery diaphragm, impact-resistant material, cushion, etc.
