ABSTRACT:
The production of C.sub.4 -C.sub.16 alkyl rubbers using the slurry process by copolymerisation of isoolefins having 4 to 16 carbon atoms with conjugated diolefins having 4 to 6 carbon atoms and/or cationically polymerisable, mono- or polyunsaturated organic compounds having 4 to 16 carbon atoms in the presence of methyl chloride and in the presence of Friedel-Crafts catalysts proceeds particularly advantageously by performing copolymerisation in the presence of linear, branched and/or cyclic alkanes.
