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) a monomer having a polymerizable unsaturated group in the molecule, the monomer (A) containing mainly a monomer having a solubility parameter of not more than 9, and 0.001-4% 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 0.5 to 70. parts by weight of (IV) at least one compound selected from the group consisting of (II) an inorganic compound having a methanol value of not less than 25% and (III) a substantially water insoluble organic acid salt, provided the sum of oil-absorbent, cross-linked polymer (I) and compound (IV) is 100 parts by weight.
一种吸油组合物,包括30至99.5份(重量)的(I)吸油交联聚合物,该聚合物由96-99.999%(重量)的(A)分子中具有可聚合不饱和基团的单体形成,该单体(A)主要含有溶解度参数不大于9的单体,以及0.001-4%(重量)的(B)交联单体,其分子中至少有两个可聚合的不饱和基团,条件是单体(A)和交联单体(B)的总和为100%,以及0.5至70. 重量份的(IV)至少一种选自(II)甲醇值不小于25%的无机化合物和(III)基本上不溶于水的有机酸盐组成的组的化合物,条件是吸油交联聚合物(I)和化合物(IV)的总和为100重量份。
