| 摘要 |
A process for the polymerization of structurally different monomers, comprising the polymerization of an ethylenically unsaturated cyclic monomer having the unsaturations in at least 1 ring of atoms, in the monomer mixture, in the presence of a metathesis-ring opening catalyst system, followed by or preceded by the polymerization of an ethylenically unsaturated monomer having the unsaturation in an open chain of atoms in the presence of a free radical forming catalyst system, both catalyst systems being present in the starting reaction mixture. Reaction mixtures to be used for this process and polymer blends to be obtained by it.
