The utilization of lignin from Pinus radiata black liquor, as a copolymer in ligninphenol-formaldehyde resin binders was studied. Methylolation, demethylation and ultrafiltration separation of high molecular-weight fractions were carried out in order to increase lignin reactivity. The different modi
## Abstract Kraft lignin from black liquor wastes have been converted into epichlorohydrinβcrosslinked beads by inverse suspension polymerization. A careful control of the different parameters allowed the preparation of spherical beads with a relatively narrow diameter size distribution. The obtain
