ABSTRACT:
Surface active agents are prepared from by-products of papermaking. According to this method, lignin, modified lignin, and mixtures thereof are reacted with a polyamine to produce an amine condensate, and this amine condensate is reacted with a bisulfite and formaldehyde in aqueous solution to produce the novel surface active agents.
