    摘要: The present invention relates to monohydroindacenyl complexes as active catalytic components in the copolymerization of ethylene. The complexes are suitable for direct preparation of ethylene copolymers having a narrow molecular distribution as well as the desired levels of low density and preferably a predetermined value of glass transition temperature Tg. The produced copolymers showing improved elastomeric performance can be prepared in a single step during polymerization reaction, thus avoiding a blending step following the polymerization step.
