Abstract

A method of removal of petroleum products from solid or liquid surfaces, in which the petroleum product is covered with a finely-divided solid polymer, said polymer being selected from the group consisting of poly(bicyclo [2.2.1]heptene-2 and poly(methyl-5 bicyclo [2.2.1] heptene-2) mainly obtained by opening the cycle of bicyclo [2.2.1]heptene-2 and its methyl derivative. After the finely-divided polymer is applied to the petroleum, there is obtained a strong solid rubbery film, the film being removable by mechanical means.
