Abstract:The purpose of this study is to valorize biomass waste
into products
with added value for indoor applications. Thus, broadleaf sawdust
was chemically processed by the solvolysis reaction in acid catalysis
in the presence of diethylene glycol at 160 °C for 4 h. After
filtration and removal of the unreacted biomass, the glycolysis product
was used in 6 different polyurethane adhesive formulations for wood
bonding. The adhesive films were characterized by FT-IR, TGA, and
DMA, while the mechanical performances wer… Show more
scite is a Brooklyn-based organization that helps researchers better discover and understand research articles through Smart Citations–citations that display the context of the citation and describe whether the article provides supporting or contrasting evidence. scite is used by students and researchers from around the world and is funded in part by the National Science Foundation and the National Institute on Drug Abuse of the National Institutes of Health.
