Macroporous hydro‐ and xero‐gels of bead cellulose, prepared by thermal coagulation of cellulose xanthate after emulsification in an organic liquid immiscible with water, and subsequent decomposition to cellulose II have been modified by crosslinking with epichlorohydrin during the process of preparation as well as afterwards in different states of drying. The changes in network structure, depending largely on the ratio of crosslinking to total add‐on of epichlorohydrin, are interpreted by the counteracting effects of a “structure tightening” and a spacer action.
