Abstract

Изобретение относится к медицине, конкретно к впитывающим изделиям, которые включают впитывающие композиции, которые демонстрируют свойства набухания, отбухания и повторного набухания. Впитывающие композиции набухают и абсорбируют жидкости после воздействия водными жидкостями, отбухают и высвобождают жидкости из набухших впитывающих композиций, а также могут повторно набухать и абсорбировать жидкости. Свойства набухания-отбухания-повторного набухания обеспечивают улучшенное распределение жидкости во впитывающих композитах и впитывающих изделиях. 2 н. и 13 з.п. ф-лы, 21 табл., 43 ил., 59 пр.
