Thermal and photochemical stability of poly(vinyl alcohol)/modified lignin blends
(Elsevier B.V., 2006-05-01)
A kraft lignin derivative (KLD) obtained by reaction with p-aminobenzoic acid/phthalic anhydride was blended with poly(vinyl alcohol) (PVA) by solution casting from DMSO. PVA and PVA/KLD films were exposed to ultraviolet ...
