Abstract
The present invention relates to methods of recovering hydrocarbons or low polarity organic chemicals from hard surfaces, water and water surfaces, in their vapor state and from porous substrates. The hydrocarbons or low-polarity organic chemicals may be included in a spill. More particularly, the invention relates to the absorption of certain hydrocarbons and low-polarity organic chemicals by applying thermoplastic elastomers of a triblock copolymer of the general configuration A-B-A. The preferred A-B-A copolymer of the invention is a low to medium molecular weight hydrogenated polystyrene-poly(isoprene+butadiene)-polystyrene or polystyrene-b-ethylene/ethylene-propylene-b-styrene block copolymer. When the elastomeric block copolymer is applied to the hydrocarbon or low-polarity organic chemical, the elastomeric block copolymer absorbs the hydrocarbons or low-polarity organic chemicals to form a mat.
