Abstract
Abstract An adhesive resin comprising the polymer of dimethyl-di-(cyclohexen-3)-yl-methane as well as a copolymer of this compound with at least one mono-or di- ethylenically unsaturated hydrocarbon or chlorinated hydrocarbon, said hydrocarbon having 4 to 12 carbon atoms. A method of making these resins and a method of causing adhesion using such resins are also disclosed, as well as compositions including this resin.
