Abstract
An adhesive binding agent based on at least one polymer of dicyclopentadiene and at least one aromatic hydrocarbon wherein the polymer comprises from 40 to 80% by weight of cyclopentadiene units and from 20 to 60% by weight of at least one aromatic hydrocarbon having a boiling point in the range from 110.degree. to 220.degree. C., selected from the group consisting of alkylaromatic hydrocarbons and tetrahydronaphthalene, said polymers having a mean molecular weight of from 300 to 5000, an iodine number (measured according to DIN Standard 53241, part 2) of from 0 to 60, and a melting point in the range of from 30.degree. to 150.degree. C., and an adhesive containing said binding agent in combination with a rubber or an ethylene-vinylacetate copolymer.
