Abstract: In present work, cationic kraft lignin (CKL) macromolecules were produced via polymerizing kraft lignin (KL) with [-2-(Acryloyloxy)ethyl] trimethyl ammonium chloride (ATAC) or [-2-(methacryloyloxy)ethyl] trimethyl ammonium methyl sulfate (METAM). Despite slightly different charge densities (2.3-2.5 mmol/g)… read more here.
