Abstract (en)

[origin: WO2019158638A1] The invention relates to a method for producing a hydrocarbon resin from at least one cyclic diolefin component and at least one ethylenically unsaturated aromatic component having 8 to 13 carbon atoms, in which method the monomer mixture is heated at a heating rate of 0.5 to 10°C/second to a polymerisation temperature of at least 180°C in order to obtain a hydrocarbon resin having a reduced proportion of by-products, the monomer mixture being substantially single-phase and liquid during the heating to at least 180°C and during the polymerisation, and the subsequently hydrogenated hydrocarbon resin exhibiting good compatibility with other constituents of hot-melt adhesives.
