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

A process for making an ethylene polymer composition,

• the process having at least two injection points and at least two polymerization reactors, each reactor having a reaction stream or zone wherein at least one catalyst system and make-up feed is injected and wherein the make-up feed comprises ethylene and optionally at least one unsaturated comonomer, and comprising continuously operating the at least two polymerization reactors and separately injecting the catalyst system and the make-up feed into the reaction stream or zone of at least one reactor,
• the composition comprising ethylene interpolymerized with at least one unsaturated comonomer and characterized as having:
• a) a melt flow ratio, I10/I2, from 8 to 10.4,
• b) a Mw/Mn of greater than 4 as determined by gel permeation chromatography,
• c) a melt index, I2, from 0.1 to 10 gram/10 minutes,
• d) a composition density less than 0.945 gram/cubic centimeter, and
• e) based on the total weight of crystallizable polymer portions, a weight percent at the dominant peak temperature above 75° C., as determined using crystallization analysis fractionation in the range of 20 to 100° C., equal to or greater than the mathematical product of 1.7946×10−28×10(31.839×composition density) for composition density in grams/cubic centimeter.
