Abstract:
A method for producing cellulose particles whereby a cellulose solution is dispersed in a regenerant or nonsolvent and the cellulose is regenerated or precipitated in dispersed form into cellulose particles.
Abstract:
Cellulose particles are described that have cationic groups in their interior. In one aspect, at least 10%, and preferably 50% or more, of the cationic groups are present within the particle interior. Also disclosed are particular combinations of such cellulose particles with certain water-soluble polymers that are well suited for use in the papermaking industry.
