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

AB  - This work presents an optimized laboratory procedure for the synthesis of zinc dimethyldithiocarbamate (Ziram) by the reaction of the sodium salt of dimethyl dithiocarbamic acid and zinc sulfate. The reaction of synthesis of the sodium salt of dimethyl-dithiocarbamic acid takes place starting from dimethylamine, carbon disulfide and sodium hydroxide solution. To the prepared acidified aqueous solution of zinc sulphate, a solution of the sodium salt of dimethyl dithiocarbamic acid was added, whereby zinc dimethyldithiocarbamate is formed in the form of a suspension. The suspension is filtered, the filter cake is washed with water to remove the sulfate ion and dried. The structure of the obtained Ziram was confirmed by IR, 1H and 13C NMR and MS instrumental methods, and the purity was determined by the classical analytical method. The obtained product zinc dimethyldithiocarbamate was ground, formulated and used in pomiculture as fungicide under the trade name Ziram.
