Narrow mwd, compositionally optimized ethylene interpolymer composition, process for making the same and article made therefrom

The invention deals with a characteristic for its narrow molecular weight distribution (MWD) and optimizing the composition uniformity of ethylene copolymer composition and a method for preparation of this combination, as well as products made from this combination. Characteristics of a new combination is, there are at least two polymer components, the first component ATREF peak and peak temperature t 1 and Mv1 viscosity-average molecular weight, while the second component ATREF t peak 2 peak temperature and viscosity-average molecular weight is Mv2, where t t peak between 1 and 2 in temperature peaks with combination density increases and decreases, while Mv1/Mv2 is less than or equal to 1.2. Another feature of a new combination is Mw/Mn is less than or equal to 3.3, by gel permeation chromatography, I10/I2 to 6.6, and composition for density less than 0.945 g/cm 3. Balanced new compounds demonstrate high toughness, good workability, and surprisingly improved optical properties, it is especially suitable for those applications where, for example, laminated film, trash can liners and heavy transport bag, especially as inflation film.
