Abstract

"PROCESSO PARA POLIMERIZAR ETILENO E/OU ETILENO EPELO MENOS UMA OU MAIS OUTRAS OLEFINAS, PELìCULA,E, ARTIGO". Um novo processo para produzir homopolímeros ecopolímeros de etileno que envolve contatar o etileno e/ou oetileno e pelo menos uma ou mais outras olefinas sob condições depolimerização com um catalisador do tipo Ziegler-Natta contendopelo menos um ou mais doadores de elétron interno, trimetilalumínioe pelo menos um ou mais doadores de elétron externo contendopelo menos uma ligação de carbono-oxigênio-carbono (C-0-C)selecionados do grupo que consiste da Fórmula (1), R^ 1^-CH~2~-0-CH~ 2~-R^ 2^, da Fórmula (2), Fórmula (3), R^ 5^-0-R^ 6^ eda Fórmula (4), R^ 7^-O(-R^ 8^-O)~ n~-R^ 9^. Também sãofornecidos películas e artigos produzidos destes."PROCESS FOR POLYMERIZING ETHYLENE AND / OR ETHYLENE AND AT LEAST ONE OR MORE OTHER OLEFINS, FILM, AND, ARTICLE". A new process to produce ethylene homopolymers and ecopolymers that involves contacting ethylene and / or ethylene and at least one or more other olefins 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 bond (C-0-C) selected from the group consisting of Formula (1), R ^ 1 ^ -CH ~ 2 ~ -0-CH ~ 2 ~ -R ^ 2 ^, of Formula (2), Formula (3), R ^ 5 ^ -0-R ^ 6 ^ and Formula (4), R ^ 7 ^ -O (-R ^ 8 ^ -O) ~ n ~ -R ^ 9 ^. Films and articles produced from them are also provided.
