Catalysts for polymerizing ethylene |
摘要 |
Catalysts for polymerizing ethylene to high yields of polyethylene having a controlled particle size are disclosed. The catalysts are prepared from new catalyst-forming components which are the reaction products of solid halogenated titanium compounds, Grignard compounds and halogenating agents. Said components, on mixing with organometallic compounds of metals belonging to Groups I-III of the Mendelyeev Periodic Table result in the catalysts capable of polymerizing ethylene to polyethylene having a controlled particle size.
