摘要

The present invention relates to a continuous process and polymerization system characterized by a separate catalyst and provide a surplus of water incorporating a composition of ethylene characterized by having a distribution of wide molecular weight distribution (MWD) and optimization homogeneity of its structure, a process for the manufacture of such a composition and an article made by this composition. The new composition is characterized as having a ratio of melting point February 10, 8 to 10.4, an Mw / Mn greater than 4 as determined by gel chromatography, a melt index I2 of 0.1 to 10 grams / 10 minutes, less than cubic 0.945 grams / centimeter, and based on the total weight of parts crystallizable polymer, a weight percent at the temperature higher dominant peak at 75 0 C, density as determined by fractionating crystallographic analysis in the range of 20 to 100 0 C, equal to or greater than the mathematical product of 1,7946x10 -28 x 10 31.839 x composition density, a density of composition in grams / cubic centimeters. The new composition shows good processability and improved toughness properties, especially excellent film strength at break and impact, and is particularly applicable for use in applications such as coating highly durable interior refuse receptacles and the manufacture of highly resistant bags.
