| titleOfInvention | Precatalysts for preparation of polyolefins and use thereof |
| abstract | What are described are precatalysts for preparation of polyolefins by homopolymerization of cyclic olefins or copolymerization of cyclic olefins with 1-olefins by means of vinyl insertion polymerization (VIP) and ring-opening metathesis polymerization (ROMP), wherein the catalysts have a borylamino structure and are represented by the following formulae (I), (II) and (III), in which: Lz is a donor molecule with the function of satisfying unsaturated sites on the metal defined as M hereinafter, where z is 0, 1, or 2; M is Ti, Zr or Hf; R groups are each independently a straight-chain or branched C1-C18-alkyl group, a straight-chain or branched C1-C18-alkoxy group, a C3-C8-cycloalkyl group, an aryl group having up to three fused or unfused rings, R' is as defined for R; X is independently F, Cl, Br, I, a straight-chain or branched C1-C18-alkyl group and/or an aryl group of the type defined above; A is carbon or silicon; D is independently H, a straight-chain or branched C1-C18-alkyl group or an aryl group of the type defined above; or AD2 is a straight-chain or branched C2-C18-alkylidene group and C is independently H or a methyl, ethyl and/or phenyl group. These precatalysts can be used particularly advantageously for the purpose described above. They allow, in the presence of a 1-olefin, at suitable temperature and suitable concentration, the preparation of a copolymer with a cyclic olefin which is incorporated into the copolymer chain by means of ROMP and VIP. |
