摘要: Abstract This study concerns the synthesis of biocomposites with kraft lignin, investigation their physicochemical properties, and tests resistance to environmental factors such as UV irradiation water. The were synthesized using bisphenol A glycerolate (1 glycerol/phenol) diacrylate (BPA.DA) a main monomer, ethylene glycol dimethacrylate (EGDMA) reactive diluent, lignin (L) an environmentally friendly filler, in curing process. Morphological analysis resulting materials was carried out scanning electron microscopy confocal microscopy. Thermal properties investigated thermogravimetric analysis. Tensile flexural performed for all obtained materials. Additionally, wettability swelling composite samples analyzed. changes observed structure polymers result aging by means ATR-FTIR analysis, optical profilometry hardness tests. results regarding effect addition on materials, particular emphasis factors, may be crucial importance further applications, inter alia UV-curable coating
