Abstract
This invention provides a highly porous crosslinked functionalised polymer having interconnected cavities of micron dimensions and having a pore volume greater than about 5.6 cc/g and having a capacity to absorb water and also to absorb saline solutions. The polymers are generally based on styrene or various acrylates or mixtures and have a functional group selected from a large range of ionic and polar compositions.
