Abstract:
A catalyst system comprising as active constituentsa) a metal complex of the formula (I) ##STR15## where the substituents and indices have the following meanings: R.sup.5 is hydrogen or a substituent selected from the group consisting of C.sub.1 -C.sub.20 -organic and C.sub.3 -C.sub.30 -organosilicon radicals in substituted and unsubstituted form, or a NR.sup.6 R.sup.7 substituent or a radical of the formula II ##STR16## where q is an integer from 0 to 20 andR', R"" is hydrogen or substituents selected from the group consisting of C.sub.1 -C.sub.20 organic and C.sub.3 -C.sub.30 -organosilicon radicals andthe further substituents in (II) as in (I) have the following meanings,M is a metal from group VIIIB of the Periodic Table of the Elements,E.sup.1, E.sup.2 are elements from group VA of the Periodic Table of the Elements,Z is an element from group VA of the Periodic Table of the Elements,R.sup.1 to R.sup.4 are substituents selected, independently of one another, from the group consisting of C.sub.1 -C.sub.20 -organic and C.sub.3 -C.sub.30 -organosilicon radicals in substituted and unsubstituted form,A', B' are C.sub.1 -C.sub.4 -alkylene units in substituted and unsubstituted form, silylene-bridged organic radicals or NR.sup.8 radicals,R.sup.6 to R.sup.8 are hydrogen or substituents selected from the group consisting of C.sub.1 -C.sub.20 -organic and C.sub.3 -C.sub.30 -organosilicon radicals,L.sup.1, L.sup.2 are formally charged or uncharged ligands,X is a formally monovalent or polyvalent anion,p is 0, 1, 2, 3 or 4,m, n are 0, 1, 2, 3 or 4,where p=m.times.n andb) one or more Lewis or protic acids or a mixture of Lewis and protic acids.
