Abstract
Polymers polymerized from an alpha-olefin monomer and a carbon monoxide monomer. The polymers include a carbon-based backbone formed from carbons of the alpha-olefin monomer and the carbon of the carbon monoxide monomer. The polymer includes in-backbone ketones formed from the carbon monoxide monomer. The in-backbone ketones may include isolated ketones, alpha-branched ketones, or both. Methods of forming the polymer and compositions containing the polymer.
Claims20
A polymer polymerized from alpha-olefin monomers and carbon monoxide monomers, the polymer comprising:
- a carbon-based backbone formed from at least a portion of the carbons of the alpha-olefin monomer and at least a portion of the carbons of the carbon monoxide monomer;
- and
- in-backbone ketones formed from the carbon monoxide monomers, the in-backbone ketones comprising isolated ketones, alpha-branched ketones, or both.
A method of making a polymer, the method comprising:
- exposing a liquid containing reaction mixture to gaseous carbon monoxide, the reaction mixture comprising an alpha-olefin monomer, a catalyst, and a solvent.
