The present invention relates to a method for preparing (co)polymers that involves reacting non-polar olefin monomers and optionally alpha -olefins having a functional group in the presence of one or more transition metal compounds of the general formula (III) and optionally in the presence of a cocatalyst. In the formula (III), the substituents and indices are as follow: R<1> and R<3> are hydrogen, C1-C10 alkyl, C3-C10 cycloalkyl, C6-C16 aryl, alkylaryl with 1 to 10 carbon atoms in the alkyl portion and 6 to 14 carbon atoms in the aryl portion, Si(R<6>)3, N(R<6>)(R<7>), OR<6>, SR<6> or R<1> and R<3> form together with C<a>, C<b> and optionally C' a five-, six- or seven-membered aliphatic or aromatic substituted or non-substituted carbon or hetero cycle; R<2> and R<4> are C4-C16 heteroaryl or C6-C16 aryl with halogeno, nitro, cyano, sulfonato or trihalogenmethyl substituents in both ortho-positions relative to N<a> and N<b>; R<5> is hydrogen, C1-C10 alkyl, C6-C16 aryl or alkylaryl with 1 to 10 carbon atoms in the alkyl portion and 6 to 14 carbon atoms in the aryl portion; R<6> and R<7> are C1-C10 alkyl, C6-C16 aryl or alkylaryl with 1 to 10 carbon atoms in the alkyl portion and 6 to 14 carbon atoms in the aryl portion; m is 0 or 1; M is a metal from the group VIIIB in the classification table; T and Q are neutral or monoanionic monodentate ligands or T and Q form together a C2 or C3 alkyl unit with a methylketone, a linear C1-C4 alkylester or a nitrile end group; A is a non-coordinating or hardly coordinating anion; x and p are 0, 1, 2 or 3; and q and n are 1, 2 or 3.
