摘要
FIELD: oil pollution removal. SUBSTANCE: block-shaped, crumbed or powdered polyurethane sorbent is product of interaction of (i) one or several polyetherpolyols with molecular weight between 300 and 6000 and containing 2 to 5 hydroxyl groups per molecule with (ii) aromatic isocyanate containing 2-3 isocyanate groups per molecule and (iii) water at weight ratio 1:(0.5-2.0): (0.083-0.25). Sorbent is characterized by apparent density up to 20 kg/cu. m and 50% fraction of pores with size not superior to 50 mcm. EFFECT: enhanced cleaning efficiency. 4 cl, 8 ex
