Abstract

"POLIETILENO PRODUZIDO PELA HOMOPOLIMERIZAçãO DE ETILENO OU COPOLIMERIZAçãO DE ETILENO COM ALFA-OLEFINAS NA PRESENçA DE UM CATALISADOR". Um polietileno produzido pela homopolimerização de etileno ou copolimerização de etileno com <244>-olefinas, na presença de um catalisador, caracterizado pelo fato de que a fração de polímeros de baixo peso molecular tendo PM <5000 g/mol é menor do que 12% em peso do polímero produzido e de que o polietileno produzido tem uma resistência em fusão medida expressa por um valor de desvio (OH) satisfazendo a expressão HO > K~ 1.<sym>0,05~ + K~ 2~, em que K~ 1~ é 9,10^ -5^ e K~ 2~ é 0,4.
