Title (EN) METHOD FOR PRODUCING HYDROGEL
(FR) PROCÉDÉ DE PRODUCTION D'HYDROGEL
(JA) ハイドロゲルの製造方法
Abstract:
(EN) The purpose of the present invention is to provide a hydrogel that has excellent mechanical strength and that does not present problems in terms of toxicity to living organisms, and a method for producing the same. This hydrogel is produced by allowing a polyvinyl alcohol-based resin (A) having a syndiotacticity of 32% or more, expressed as triads, to swell in water (B), dissolve under thermocompression conditions, and then cool.
(FR) La présente invention vise à procurer un hydrogel qui présente une excellente résistance mécanique et qui ne présente pas de problèmes en termes de toxicité envers les organismes vivants, ainsi qu'un procédé de production de ce dernier. Cet hydrogel est produit en laissant une résine à base d'alcool polyvinylique (A) présentant une syndiotacticité de 32 % ou plus, exprimée en triades, gonfler dans de l'eau (B), se dissoudre dans des conditions de thermocompression, puis refroidir.
(JA) 本発明は、優れた機械的強度を有し、生体に対する毒性の問題がないハイドロゲル及びその製造方法を提供することを目的とする。ハイドロゲルを、シンジオタクティシティがトライアッド表示で32%以上のポリビニルアルコール系樹脂(A)を水(B)に膨潤させ、加熱圧縮条件下で溶解し、その後放冷することにより製造する。
