  • Biocompatible, biodegradable, water-absorbent material and methods for its preparation
    Patent number: 6833488
    Abstract: A bio-compatible, biodegradable macromolecular water-absorbent polymeric material having a three-dimensional configuration with intermolecular covalent bonds and containing free functional groups selected from OH, SH, NH2, and COOH. The polymer is formed by polymer-polymer inter-coupling interaction between a natural water-soluble polymer A or its derivatives having a molecular weight between 20,000 and 500,000 Da, and a synthetic polymer B in a ratio of A:B of 15:85 to 85:15.
