Hydrocarbon Resin and Method for Production Thereof
20230183389 · 2023-06-15 ·

The invention relates to a method for producing a hydrocarbon resin, in which method a monomer mixture which contains an aromatic component containing indene and/or C.sub.1-4 alkylindene and a cyclic diolefin component containing a cyclic diolefin compound is polymerized by heating to a polymerization temperature of at least 180° C. to obtain a product stream containing hydrocarbon resin, wherein oligomers which contain units originating from the cyclic diolefin compound and/or units originating from the aromatic component are separated from the product stream and returned to the monomer mixture, and wherein the hydrocarbon resin is heated in an annealing step to a temperature of 150° C. to 300° C. for a period of 15 minutes to 240 hours. The invention also relates to a hydrocarbon resin that is obtainable by the method, to a hydrogenated hydrocarbon resin, and to the use of the hydrocarbon resin and the hydrogenated hydrocarbon resin.
