## Abstract This work was focused on the production and characterization of microcellular polyurethane (PU) composites reinforced with pine woodβfibers or with hemp, which can be applied to the manufacture of car interior panels, or acoustic insulation panels for the construction industry. The poly
Phosphorus-containing polyurethanes (PU-P) based on bisphenol-AF were synthesized by N-alkylation in a two-step process. First, the polymer was metalated with sodium hydride; then the prepared urethane polyanion was treated with diethyl 2-bromoethyl phosphate. IR spectra exhibited characteristic ab
