Broad mwd, compositionally uniform ethylene interpolymer compositions, process for making the same and article made therefrom

Characteristics of the invention involves a catalyst and supplementary feeding is continuous methods and aggregation of separate injection systems, feature lies in the broad molecular weight distribution (MWD) of ethylene copolymer composition uniformity and optimal body composition, preparation method and by the combination of this combination of manufacturing of products. By in new combination property features is melt body mobile than I10/I2 for 8 to 10.4; through coagulation rubber penetration color spectrum law determination of Mw/Mn is greater than 4; melt body index I2 for 0.1 to 10G/10min; density below 0.945g/cm3; and based on can Crystal polymer part of total weight, in 20-100 ℃ range within with Crystal Analysis fractionation determination of in above 75 ℃ of peak temperature Xia of weight percentage is equal to or is greater than on to g/ Cm3 is a product of the combination of density of mathematics 1.7946x10-28x10 (31.839x combination of density). The new compounds demonstrate good processing and improvement of toughness, especially very good tear resistance and impact resistance of thin films, especially suitable for high performance metal trash cans and heavy loads in the village such as cargo bags and other applications.
