| abstract |
A novel process for producing homopolymers and copolymers of ethylene which involves contacting ethylene and/or ethylene and at least one or more other olefin(s) under polymerization conditions with a Ziegler-Natta type catalyst containing at least one or more internal electron donors, trimethylaluminum and at least one or more external electron donors containing at least one carbon-oxygen-carbon linkage (C-O-C) selected from the group consisting of Formula (1), R1-CH2-O-CH2-R2, Formula (2), Formula (3), R5-O-R6, and Formula (4), R?7-O(-R8-O)¿n-R9. Also provided are films and articles produced therefrom. |
