Abstract
An oil-absorbent composition including 30 to 99.5 parts by weight of (I) an oil-absorbent, cross-linked polymer formed from 96-99.999% by weight of (A) monomer having a polymerizable unsaturated group in the molecule, said monomer (A) containing mainly a monomer having a solubility parameter of not more than 9, and 4-0.001% by weight of (B) a cross-linking monomer having at least two polymerizable unsaturated groups in the molecule, provided the sum of monomer (A) and cross-linking monomer (B) is 100%, and 70 to 0.5 to parts by weight of (IV) at least one compound selected from the group consisting of (II) inorganic compounds having a methanol value of not less than 25% and (III) substantially water insoluble organic acid salts, provided the sum of oil-absorbent, cross-linked polymer (I) and compound (IV) is 100 parts by weight.
