(KO) 고흡수성 수지의 제조 방법 및 이를 통해 제조된 고흡수성 수지
Abstract: front page image
(EN)The present invention relates to a method for preparing a super-absorbent resin. The method for preparing a super-absorbent according to the present invention can produce a super-absorbent resin, which has a fast absorption rate and high permeability while having excellent absorption characteristics, such as water retention capacity and absorbency under pressure, by using a polycarboxylic acid-based copolymer at the time of polymerization of a hydrous gel phase polymer.
(FR)L'invention concerne un procédé de préparation d'une résine superabsorbante. Le procédé de préparation d'un superabsorbant selon la présente invention peut produire une résine superabsorbante, qui présente une vitesse d'absorption rapide et une perméabilité élevée tout en présentant d'excellentes caractéristiques d'absorption, telles que la capacité de rétention d'eau et un pouvoir absorbant sous pression, par l'utilisation d'un copolymère à base d'un poly(acide carboxylique) au moment de la polymérisation d'un polymère en phase de gel hydraté.
(KO)본 발명은 고흡수성 수지의 제조방법에 관한 것으로, 본 발명에 따른 고흡수성 수지의 제조 방법은 함수겔상 중합체 중합시 폴리카르복시산계 공중합체를 사용함으로써, 보수능 및 가압 흡수능과 같은 흡수 특성이 우수하면서도 빠른 흡수 속도와 높은 투과도를 가지는 고흡수성 수지를 제조할 수 있다.
