Abstract
An ethylene-butene copolymer prepared from ethylene monomer and butene monomer, the ethylene-butene copolymer including at least 78 mole % ethylene and no greater than 22 mole % butene, and a hot melt adhesive composition including from 40% by weight to 90% by weight of the ethylene-butene copolymer, tackifying agent, and wax.
Claims14
A hot melt adhesive composition comprising:
- ethylene-butene copolymer prepared from ethylene monomer and butene monomer, the ethylene-butene copolymer having a polydispersity index of from 2 to 6 and comprising
- at least 78 mole % ethylene, and
- no greater than 22 mole % butene.
A method of making an adhesive composition, said method comprising:
- preparing an ethylene-butene copolymer having a polydispersity index of from 2 to 6 and comprising at least 78 mole % ethylene, and no greater than 22 mole % butene;
- transferring the copolymer to a mixer;
- and
- combining at least one of tackifying agent, wax, and antioxidant with the copolymer.
A method of making an ethylene-butene copolymer, the method comprising:
- polymerizing ethylene monomer and butene monomer to form an ethylene-butene copolymer having a polydispersity index of from 2 to 6, the ethylene-butene copolymer comprising at least 78 mole % ethylene and no greater than 22 mole % butene.
A method of making an adhesive composition, said method comprising:
- transferring an ethylene-butene copolymer in the form of a liquid to a mixer, the ethylene-butene copolymer having a polydispersity index of from 2 to 6 and comprising at least 78 mole % ethylene, and no greater than 22 mole % butene;
- and
- adding at least one of tackifying agent, wax, and antioxidant to the copolymer.
