METALLOCENE CATALYST AND METHOD FOR PRODUCTION OF COPOLYMER OF CYCLOOLEFINS, MOLD ARTICLE AND POLYMER ALLOY COMPRISING AT LEAST ONE CYCLOOLEFIN POLYMER

摘要

FIELD: production of cycloolefin copolymer. SUBSTANCE: proposed metallocene catalyst represent metallocene compound having ligands except those metallocene compounds with 4-(η⁵-3-alkyl cyclopentadienyl)-4,6,6-trimetyl-η⁵-2-alkyl-4,5- tetrahydropentalene ligands. At least two of substituted or unsubstituted cyclonentadienyl groups being bound by mono- or polycyclic system are used as said ligand, where at least one cyclopentadienyl group is linked with mono- or polycyclic system. Olefin copolymer is prepared by polymerization at least one cycloolefin with the help of said metallocene catalyst. The process is followed by isolation of desired polymer by common way. EFFECT: improves quality of desired product, improves efficiency of the method.
