Abstract: The research findings confirmed that the still bottom residue comprises numerous valuable components, including naphthalene, specialized resins, and various other valuable compounds.Naphthalene was successfully isolated from heavy pyrolysis tar, a recognized residue of petrochemical production, utilizing picric acid (trinitrophenol).Subsequent to its isolation, -chloromethyl naphthalene was synthesized from it.The synthesized -chloromethyl naphthalene holds potential for use as a raw material in producing various valuable compounds, including additives that enhance the properties of composite materials.To this end, compositions were prepared based on styrene-butadiene rubber modified with -chloromethyl naphthalene at various ratios, and the effect of -chloromethyl naphthalene as a modifier on the physico-mechanical and chemical properties of these compositions was evaluated.Initially, binary blends were prepared by mixing styrene-butadiene rubber (SK-30 ARKM-15) with -chloromethyl naphthalene at different ratios on a roll mill at 40-60 o C. Subsequently, after treating the binary blend in an IIRT-5 device under vulcanization conditions (at a temperature of 1552 o C for 20 min), the gel fraction was determined to be 92% by extracting the sample in acetone and toluene for 20 h.Following extraction, the samples were dried to constant weight and then subjected to IR spectral analysis.The properties of the compositions prepared using these SBR -chloromethyl naphthalene binary blends were thoroughly investigated.The investigation results revealed a significant improvement in the properties of the SBR-based composition modified with 4-6 parts by weight of -chloromethyl naphthalene compared to the unmodified SBR composition.This enhancement in the modified composition's properties suggests that the modifier induces structural changes within the rubber matrix during the vulcanization process
