Abstract:
     The present invention provides a microcellular polymeric absorber with good water-holding ability and compressibility. The process for manufacture comprises foaming the products of reaction of polyamino ether with epoxy resin, then making the resulting products go to quaternary-amination by agents such as acid. The polymeric material is especially useful to absorb liquid.
