This article presents the optimization of sulfur-cellulose composite (SCC) synthesis via inverse vulcanization using waste elemental sulfur (𝑆8 ) and activated cotton husk. A three‑factor Box-Behnken design was applied (factors: temperature 160-190°C, time 90-180 min, S:Org mass ratio 40:60-60:40). Regression models were built for three responses: product yield (𝑌1 ), onset decomposition temperature (𝑌2 , 𝑇𝑜𝑛𝑠𝑒𝑡 ), and fluid loss reduction efficiency (𝑌3 ). All three factors significantly affect composite properties, with temperature being dominant. Optimal synthesis conditions were: T = 185°C, τ = 135 min, S:Org = 55:45. Under these conditions, the composite exhibited a yield of 91.8%, 𝑇𝑜𝑛𝑠𝑒𝑡 = 272°C, and fluid loss reduction of 62.5%. The use of a catalyst (hexamethylenetetramine, 1 wt% of sulfur) increased yield by 6.6% and thermal stability by 24°C compared to non‑catalyzed synthesis. The composite was characterized by FTIR, TGA, XRD, and SEM-EDX, confirming its formation. The obtained composite is recommended as a thermostable additive for drilling fluids at temperatures up to 180°C.
