ABSTRACT:
For producing 100 parts by weight of a polymer blend 0 to 95 parts by weight of a finely divided polyolefin, 0 to 95 parts by weight of finely divided cycloolefin polymer and 0.1 to 99 parts by weight of a blockpolymer (which consists of monomeric units derived from norbornen and monomeric units derived from aliphatic monocycloolefins C.sub.n H.sub.2n and/or aliphatic 1-olefin, such as ethylene or propylene, are mixed and the mixture is processed under heat and shear forces. The block copolymer acts as phase mediator and contains in different blocks different proportions of the monomer units used.
