The present invention relates to a treating agent suitable for quickly solidifying, recovering and removing oil that has leaked out during transportation and storage on the ground or leaked at a work place.

Description of the Related Art With the recent increase in petroleum consumption, the number of leak accidents during mining, transportation and storage increases, and the scale of the accident tends to increase. Also, oil leaks are constantly occurring in Offshore (offshore) oil fields, natural gas fields, and oil shipping ports. Due to such accidents, not only the enormous economic burden on the accident party but also the influence on the biological system due to environmental pollution has become a serious problem.

ていない。A well-known oil adsorbent is an amino acid-based product, but its hardness is insufficient to recover the gelled product after adsorption with a tool such as a net. Since dibenzylidene sorbitol dissolved in an organic solvent as a synthetic organic substance is flammable, it is difficult to handle and the solvent itself becomes a pollution source. Although the powdery material of polynorbornene is a product with few defects, it is costly and not suitable for use in a large amount.

It has been known. For example, U.S. Pat. No. 3,518,183 discloses polystyrene / polyisoprene block copolymers.
Is proposed. In addition, Japanese Patent Publication Sho 49-1303
In the invention described in Japanese Patent Publication No. 69, polystyrene-polybutadiene block copolymer is said to be preferable, and it is stated that one of the terminals of the molecular structure is a polybutadiene phase.

Adsorption occurs at the same time as charging, but if kerosene is present in excess, the interface between unadsorbed kerosene and solidified matter is always soft, and recovery of the solidified matter is somewhat difficult. However, in the combination of styrene / butadiene composition ratio of the copolymers of 20/80 and 45/55, the larger the molecular weight of both copolymers, the better the adsorption amount and the hardness of the solidified product. In this combination, the weight of the solidified product after standing for 30 minutes was 25 gr.
