The invention relates to (co)polymers obtainable by polymerization of cationically polymerizable monomers in the presence of a novel initiator system consisting of an initiator component formed by an active chlorine-containing aliphatic low-molecular mass, oligomeric and/or polymeric substance and a Lewis acid, selected from boron trichloride and titanium tetrachloride either alone or in ad-mixtures with ferric chloride. The polymers contain the chemically bound initiator component corresponding to the used active chlorine-containing organic substance.
