Polyethylene Copolymers with Vinyl Terminated Macromonomers as Comonomers

摘要

This invention relates to polyethylene copolymers comprising ethylene and vinyl terminated macromonomers. The polyethylene copolymers are achieved by copolymerization of ethylene and vinyl terminated macromonomers in a polymerization reactor, particularly in high yields and with a wide range of VTM molecular weights, that can be made at commercial rates.

主权项

1. An ethylene copolymer comprising at least 70 wt % of ethylene and at least one vinyl terminated macromonomers (VTM) wherein the ethylene copolymer has: 1) a Mw of 100,000 g/mol or more; 2) a density of 0.94 g/cm3 or less; and 3) a ratio of the complex viscosity at a frequency of 0.1 rad/s to the complex viscosity at a frequency of 100 rad/s of 15 or more.
