AB  - This paper investigates the using potential of acryl-functionalized kraft lignin (AKL) in reducing the
flammability of polymer composites based on recycled unsaturated polyester resins (UPR). Acryl functionalization of
kraft lignin was performed by direct esterification of free polyphenolic groups with acryloyl chloride, after what, the
AKL was blended in UPR resin synthesized from the polyols obtained by catalytic depolymerization of waste
poly(ethylene terephthalate). The AKL was homogenized in UPR resin in different weight ratios: 2.5, 5.0, 7.5, and 12.5
wt.%. Structural and dynamic-mechanical characteristics of acryl-functionalized kraft lignin and composites were
determined using FTIR spectroscopy, dynamic-mechanical analysis (DMA), and tensile tests. The influence of
functionalization and mass fraction of AKL on tensile and thermal properties of UPR resin was studied. The thermal
properties of the composite were tested according to the standard UL-94 method, based on which the highest category
of heat-resistant materials is a composite with 12.5 wt.% acyl-functionalized lignin.
