Abstract
The invention provides an ethylene-based polymer formed from at least the following: ethylene and a “monomeric chain transfer agent (monomeric CTA),” comprising a “copolymerization end” and a “chain transfer end.”
Claims11
An ethylene-based polymer formed from ethylene and at least one monomeric chain transfer agent (monomeric CTA) comprising a copolymerization end and a chain transfer end;
- wherein the polymer comprises a majority amount of polymerized ethylene, based on the weight of the polymer;
- and
- wherein the chain transfer end of the monomeric chain transfer agent is selected from the group consisting of the following 1) through 4):
- where R1 is selected from H, C1-C22 alkyl, C3-C8 cycloalkyl, CN, Phenyl, COCH3, Cl, Br, or I;
- where R2, R3 are each independently selected from H, C1-C22 alkyl, C3-C8 cycloalkyl, CN, Phenyl, or COCH3;
- where n is from 1 to 6;
- where R4 is selected from H, C1-C22 alkyl, C3-C8 cycloalkyl, Phenyl, Cl, Br, or I;
- and wherein the ethylene-based polymer comprises ethylene and said at least one monomeric CTA as the only monomeric units.
