    • An improved process for the production of polymers having halogen end groups from cationically polymerizable monomers, the monomer being polymerized in an inert solvent at a temperature of from +10.degree. to -130.degree. C. using a catalyst system consisting of a metal halide and an organic halide, compounds corresponding to the following general formula being used as organic halides: ##STR1## wherein X represents a halogen atom;R.sub.1, R.sub.2, R.sub.3, represent C.sub.5 -C.sub.10 cycloalkyl, or a C.sub.1 -C.sub.20 straight- or branched-chain alkyl or ##STR2## wherein R.sub.4 and R.sub.5 represent C.sub.5 -C.sub.10 -cycloalkyl or a C.sub.1 -C.sub.20 straight- or branched-chain alkyl;and the organic halide has at least 5 carbon atoms and at most 50 carbon atoms and is in a concentration of from 10.sup.-1 to 10.sup.-6 mols per mol of monomer, while BX.sub.3, SnX.sub.4, TiX.sub.4, SbX.sub.5 or FeX.sub.3, wherein X is fluorine, chlorine, bromine or iodine, is used as metal halide in from 2 to 500 times molar excess, based on the organic halide.
