摘要

"Interpolu00ecmero compositions of ethylene comcomposiu00e7u00e3o uniform, wide distribution depeso molecular, process for making the same eartigos made of the same.The present invention refers to sea a continuous process and polymerization system caracterizadopela injection separated from catalyst and feeding deconstituiu00e7u00e3o,A composition of interpolu00edmero of etilenocaracterizada for both, distribution of molecular weight (MWD) and uniformity of the composition is optimized.A process for fazeresta composition and an article manufactured from the composition.Acomposiu00e7u00e3o new is characterized by having a proportion of fluxode merger, I ~ 1 ~ / I ~ 2 ~ 8 to 10.4, m ~ w / M ~ n ~ larger than 4 as determined by permeation chromatography degel,An index of fusion, I ~ 2 ~, from 0.1 to 10 grams / 10 minutes, a density lower than 0945 grams / cubic centimeter, ebaseada total weight of portions of polymer cristalizu00e1veis,Umaporcentagem in weight in the dominant peak temperature above de75 198 C, as determined using deanu00e1lise fractionation crystallization in the range of 20 to 10 198 C,The product of oumaior mathematical 1.7946x10 ^ - 28 ^ x 10? (31.839x density composition)? For the density of the composition emgramas / cubic centimeter.The composition further exhibits improved hardness and boaprocessabilidade properties, especially excellent resistance to tearing of the film eimpacto,And is particularly well suited for use emaplicau00e7u00f5es such as coatings for trash bags and transportation for heavy work of high performance.
