Title (EN) ABSORBING RESIN PARTICLES, PROCESS FOR PRODUCING SAME, AND ABSORBENT AND ABSORBING ARTICLE BOTH INCLUDING SAME
(FR) PARTICULES DE RÉSINE ABSORBANTE, LEUR PROCÉDÉ DE PRODUCTION, ET AGENT D'ABSORPTION ET ARTICLE ABSORBANT LES COMPRENANT
(JA) 吸収性樹脂粒子、この製造方法、これを含む吸収体及び吸収性物品
Abstract:
(EN) Absorbing resin particles having an absorption rate pattern in which the absorption rate is low in the initial stage, normal in the middle stage, and high in the late stage. An absorbing article causing no problems such as a rash is provided by using the absorbing resin particles. The absorbing resin particles comprise a crosslinked polymer (A1) comprising units of a water-soluble vinyl monomer (a1) and/or a hydrolyzable vinyl monomer (a2) and units of a crosslinking agent (b), as essential structural units. In a swelling volume measurement method in which the swelling volume per g of the absorbing resin particles in saline is measured, the ratio of the time period to a swelling volume of 5 mL (t1) to the time period to a swelling volume of 40 mL (t2), t2/t1, is 5-20.
(FR) L'invention concerne des particules de résine absorbante ayant un profil de taux d'absorption selon lequel le taux d'absorption est bas au stade initial, normal au stade médian et élevé au dernier stade. L'invention concerne un article absorbant qui ne génère pas de problèmes de peau, tels que l'érythème fessier, grâce à l'utilisation des particules de résines absorbantes. Les particules de résine absorbante comprennent un polymère réticulé (A1) comportant des unités d'un monomère de vinyle soluble dans l'eau (a1) et/ou d'un monomère de vinyle hydrolysable (a2) et des unités d'un agent de réticulation (b) telles que des unités structurales essentielles. L'invention concerne également un procédé de mesure d'une augmentation de volume selon lequel on mesure l'augmentation de volume en g des particules de résine absorbante dans une solution saline, le rapport de la durée à une augmentation de volume de 5 ml (t1) à la durée d'une augmentation de volume de 40 ml (t2), t2/t1, étant compris entre 5 et 20.
(JA)  吸収速度パターンが初期遅く、中期普通、後期速くの吸収性樹脂粒子が提供でき、この吸収性樹脂粒子を使用することで、カブレ等の問題を生じない吸収性物品を提供する。 本発明は、水溶性ビニルモノマー(a1)及び/又は加水分解性ビニルモノマー(a2)、並びに架橋剤(b)を必須構成単位とする架橋重合体(A1)を含んでなる吸収性樹脂粒子であって、吸収性樹脂粒子1g当たりの生理食塩水に対する膨潤容積測定法において、膨潤容積が5mlに達するまでの時間(t1)と、膨潤容積が40mlに達するまで時間(t2)の比(t2/t1)が5~20である吸収性樹脂粒子である。
