Abstract
A composition comprising vinyl-terminated polyethylene having an Mn from about 200 g/mol to about 10,000 g/mol; and a comb polyolefin having polyethylene arms attached to a random copolymer backbone, said backbone including units derived from an alpha-olefin having 3 or more carbon atoms, where the polyethylene arms have an Mn from about 200 g/mol to about 10,000 g/mol, and where the comb polyolefin has an Mp from about 7,500 to about 400,000 g/mol.
Claims6
A composition comprising:
- (i) from about 5 to about 50 wt % of a vinyl-terminated polyethylene having an Mn from about 200 g/mol to about 10,000 g/mol;
- and
- (ii) from about 50 to about 95 wt % of a comb polyolefin having polyethylene arms attached to a random copolymer backbone, said backbone including a majority of units derived from propylene, as determined by molar percentage of units,
- wherein the polyethylene arms have an Mn from about 200 g/mol to about 10,000 g/mol, and
- wherein the comb polyolefin has an Mp from about 7,500 to about 400,000 g/mol.
