METHOD FOR PRODUCING ELASTOMERS |
摘要 |
Elastomers can be produced by (co)polymerising monomers from the group of C2-C8- alpha -olefins, C4-C15-diolefins and other monomers in the solid phase, in solution, as a slurry or in gas phase where metallocene compounds or pi -complex compounds of formulas (I) or (XIII) are used as catalysts, in which CpI and CpII represent carbanions with a structure containing cyclopentadienyl, pi I and pi II represent charged or electrically neutral pi -systems, D represents a donator atom and A an acceptor atom, wherein D and A are linked by a reversible, coordinate bond such that the donator group adopts a positive (partial) charge and the acceptor group a negative (partial) charge, M stands for a transition metal of the IIIrd, IVth, Vth or VIth subgroup of the periodic system of elements including lanthanides and actinoides, X stands for an anion equivalent and n, depending on the charge of M, is 0, 1, 2, 3 or 4.
