Abstract

"PROCESSO PARA A POLIMERIZAçãO DE ETILENO E PELO MENOS UMA OU MAIS OLEFINA(S) PARA PRODUZIR UM INTERPOLìMERO DE ETILENO/OLEFINA, PRODUTO DE INTERPOLìMERO ETILENO/OLEFINA FILME E, ARTIGO". é descrito um processo para a produção de interpolímeros de etileno/olefina os quais, para um dado índice de fusão e densidade, possuem uma temperatura de pico de fusão (T~ m~) reduzida. O processo envolve colocar em contato o etileno e pelo menos uma outra olefina, em condições de polimerização, com um catalisador para polimerização de olefina e pelo menos um modificador que compreende pelo menos um elemento do Grupo 15 e/ou Grupo 16, em uma quantidade suficiente para reduzir a temperatura de pico de fusão do interpolímero de etileno/ olefina. Também descritos aqui estão os interpolímeros de etileno/olefina resultantes do processo.
