| Popis: | The studies devoted to the synthesis of ternary copolymers of ethylene, propylene, and nonconjugated cyclic dienes on single-site catalytic systems of a new generation based on metallocene complexes, “constrained geometry” complexes, and monocyclopentadienyl and post-metallocene chelate IVB-group complexes have been analyzed. The advantages and disadvantages of these catalytic systems have been compared with traditional vanadium catalysts introduced into production in the 1960s and used to date in the industrial synthesis of rubbers. A significant part of the review is devoted to the analysis of patent publications, especially in recent years, belonging to the main world producers of ethylene–propylene–diene rubbers. |
