Production of homocopolymers, co-polymers or block copolymers from cycloolefinicmonomer units

摘要: The invention relates to the production of homopolymers, co-copolymers or block copolymers from cycloolefinic monomer units characterized in that polymerization occurs presence a catalyst general formula (I), and optionally an additive, wherein substituents indices have following meaning: M is metal group VIII B periodic table elements; E 1 , 2 are independently each other element V A Z bridging structural unit; Ar stands for annelated aryl independent other; L formally uncharged Lewis base ligands; X means monovalent bivalent anions; k 2; l, m, n represent 2, whereby m×n=1.
