HYDROXYALCOYLATED CROSSLINKED REGENERATED CELLULOSE AND PROCESS FOR PREPARING THE SAME

摘要

P THE INVENTION RELATES TO A HYDROXYALCOYLATED CROSSLINKED REGENERATED CELL AND ITS PREPARATION METHOD. /P P THIS CELLULOSE IS THE REACTION PRODUCT OF REGENERATED CELLULOSE WITH: A. UP TO 20 (CELLULOSE VOLUMEPOIDS) CROSSLINKING AGENT COMPRISING A BIFUNCTIONAL COMPOUND OF FORMULA XRY IN WHICH X AND MAY BE THE SAME OR DIFFERENT AND EACH INDEPENDENTLY REPRESENT A HALOGEN OR EPOXY GROUP AND R REPRESENTS AN ALIPHATIC RESIDUE, AND WITH BULKENESS OF 100%. HYDROXYALCOYLING AGENT. /P P THIS REGENERATED CELLULOSE IS INFLATABLE IN WATER, HYDROPHILIC, INSOLUBLE IN WATER AND MAY BE ADVANTABLY USED TO FORM THE MATRIX OF A CATIONIC SULFATE ION EXCHANGER. /P
