Proceedings for posters presentations. [S.l.: s.n.], 2018. p. 399-402.c2018  aThe subs titution of phenol by lignin in phenol-formaldehyde (PF) resins is one of most promis ing end uses for lignin valorization. lignin from grasses and softwood has been the focus of the studies in this field as they present higher number of theoretical reactive sites for the resin synthesis.
