Abstract
The present disclosure provides a composition. In an embodiment, the composition is an ethylene-based polymer composition formed by high pressure (greater or equal to 100 MPa) free radical polymerization. The ethylene-based polymer composition includes ethylene monomer and a mixture of hydroxyl-terminated polybutadiene molecules (PB-OH). Each PB-OH molecule includes internal alkene groups and terminal alkene groups. Each PB-OH molecule has more internal alkene groups than terminal alkene groups.
Claims15
An ethylene-based polymer composition formed by high pressure (greater or equal to 100 MPa) free radical polymerization comprising:
- ethylene monomer and a mixture of hydroxyl-terminated polybutadiene molecules (PB-OH), each PB-OH molecule comprising internal alkene groups and terminal alkene groups, each PB-OH molecule having more internal alkene groups than terminal alkene groups.
A process comprising:
- reacting, in a polymerization reactor under free-radical polymerization conditions and at a pressure greater than or equal to 100 MPa, ethylene monomer and a mixture of hydroxyl-terminated polybutadiene molecules, each molecule having the Structure I
- wherein c is from 0 to 90, n is from 0 to 90, t is from 0 to 90, and
- c+n+t>=4 with the proviso that c, n, and t each simultaneously cannot be 0;
- and
- forming an ethylene-based polymer composition.
