Abstract
The present invention relates to a branched modifier and a composition comprising more than 25 wt % (based on the weight of the composition) of one or more linear ethylene polymers having a g′vis of 0.97 or more and an Mw of 20,000 g/mol or more and at least 0.1 wt % of a branched modifier where the modifier has a g′vis of less than 0.97, wherein the ethylene polymer has a g′vis of at least 0.01 units higher than the g′vis of the branched modifier.
