Abstract

Black liquor is formed as a side product of the pulping industry, and typically it is used as a source of energy for the mill. Black liquor contains a significant amount of carboxylic acids, which have low heat values. Therefore, the carboxylic acids may be separated from black liquor and valorized in a number of biopolymer applications. In this study, several black liquor fractions were polymerized and the obtained polymers were characterized. The fractions were, for the first time, successfully polymerized. Polymers with Tg -1-49 °C and Mw 750-2400 g/mol were obtained. The best results (Tg 49 °C, Mw 2400 g/mol) were obtained using fraction, which had the most even OH/COOH ratio. Potential applications for the polymeric materials obtained from black liquor are foreseen to be, hotmelt adhesives, plastizicer and thermosets or functional materials after further modification of OH-groups.
