Recycled Biomass Waste as Copolymerization Partners

Abstract

Taking into account the main demand regarding environmental protection and the need for wood preservation, our research has been focused on the development of some new chemical agents for wood preservation, based on acrylic copolymers and lignosulfonates, biomass waste, generated as by-products of chemical wood pulping. Because the lignosulfonates possess a reactive chemical potential, evidenced by the presence in their structure of some functional groups, they have been used as reactive comonomers in water emulsion copolymerization of acrylic comonomers. Having in view the biocide activity of acrylic comonomers and lignosulfonates, the obtained copolymers were biologically investigated and proposed as ecological wood preservatives.
