摘要：Transition metal complexes of formula LmMXn (I) are new; in which M = titanium (Ti), zirconium (Zr), hafnium (Hf), vanadium (V), niobium (Nb), tantalum (Ta) or a lanthanide (Ln); X = fluorine (F), chlorine (Cl), bromine (Br), iodine (I), hydrogen (H), 1-10C alkyl, 6-15C aryl or OR<1>; R<1> = 1-10C alkyl, 6-15C aryl or an alkylaryl, arylalkyl, fluoroalkyl or fluoroaryl group with 1-10C alkyl and 6-20C aryl groups; m = 1 or 2; n = 4-m if M = Ti, Zr or Hf or n = 5-m if M = V, Nb or Ta or n = 3-m if M = Ln; L = a ligand of formula (II); A = a bridging group completing a 5- or 6-membered, optionally substituted aromatic ring, which may also contain 2 other hetero-atoms selected from oxygen, sulphur and nitrogen and may be anellated with another 2-, 3- or 4-ring iso- or hetero-aromatic system; R<2>, R<4> = H, 1-10C alkyl, 6-15C aryl, tri-(1-10 C)-alkylsilyl or tri-(6-15C)-arylsilyl; R<3> = 6-15C aryl, 6-15C fluoroaryl, 1-10C alkyl or 1-10C fluoroalkyl with no H on the alpha -C atom. Also claimed are (i) beta -diketimines of formula (IIA); (ii) a method for preparing polymers from 2-10C alk-1-enes using a catalyst system containing (I); and (iii) fibres, films
and mouldings made from these polymers.
