Abstract

공극 공간에 의해 분리된 상호연결된 스트랜드 형태의 다공성 흡수 거대구조체를 갖는 흡수성 물질. 다공성 거대구조체는 양이온성, 바람직하게는 중합체성 아미노-에피클롤로하이드린 부가물로 가교결합된 표면을 갖는 상호연결된 흡수성 겔화 입자를 갖는다. 물 또는 신체 배설물(예, 뇨)과 같은 액체와 접촉하면, 다공성 흡수 거대구조체는 팽윤되고, 상기 액체를 흡수할 수 있다. 흡수성 물질은 바람직하게는 기재, 바람직하게는 셀룰로즈 기재를 포함하며, 이는 다공성 거대구조체의 표면중 한면 또는 양면에 결합된다.
흡수성 물질은 기저귀, 성인 실금자용 패드 및 생리대와 같은 흡수 제품에 유용하다.
