Cationic kraft lignins at temperatures beyond 250 ; nonetheless, this really is clearly outmatched by improved compatibility with polar materials, which include biopolymer-based matrices. Moreover, introduction of your quaternary ammonium moieties is expected to impart hardwood kraft lignin antimicrobial activity, as is known from microbicidal finishing of textiles or modification of starch employing comparable reagents. Respective tests are subject of ongoing investigations. FRAP antioxidant activity measurementsPatr ia I. F.
