Abstract
The present invention relates to polyethylene compositions comprising one or more ethylene polymers and one or more dendritic hydrocarbon polymer modifiers, in particular, this invention further relates to polyethylene blends comprising one or more ethylene polymers and one or more dendritic hydrocarbon polymer modifiers, wherein the modifier has: 1) a g′ value less than 0.75; 2) a Cayley tree topology with a layer number of 2 or more more; and 3) a average Mw between the branch points of 1,500 g/mol or more.
Claims24
A polyethylene blend comprising one or more ethylene polymers and one or more dendritic hydrocarbon polymer modifiers, wherein the modifier has:
- 1) a g′vis value less than 0.75;
- and 2) a Cayley tree topology with a layer number of 2 or more.
A composition comprising more than 25 wt % (based on the weight of the composition) of one or more ethylene polymers having a g′vis of 0.95 or more and an MW of 20,000 g/mol or more and at least 0.1 wt % of a dendritic hydrocarbon polymer modifier where the modifier has a g′vis of less than 0.75, wherein the ethylene polymer has a g′vis of at least 0.20 units higher than the g′vis of the branched modifier.
