Abstract
The invention relates to an amphiphilic multiblock copolymer capable of forming non-covalent crosslinks. The non-water soluble copolymer, having a hydrophilic middle block and hydrophobic end blocks, has a high water transmission or permeation. The copolymer can be used in applications requiring absorption and/or transmission of fluids, the preferred fluids being water or hydrophilic liquids such as glycerin, glycols, and alcohols. One specific use of the amphiphilic multiblock copolymer is as a hydrogel material.
