Brief Description
This invention is a method includes mixing a polymer with one or more dehydrogenating reagent(s), thereby forming the dehydrogenated polymer. Such a dehydrogenated polymer can then be made into a alkene or a dehydrogenating polymer.
Suggested uses
The conversion of polyolefins to small molecules (e.g., monomers) would enable the largest fraction of waste plastic to be a carbon feedstock, but such a task requires cleavage of carbon-carbon bonds that often resist selective chemical transformations. This invention does just this and recycles plastic for further use.
Advantages
This invention is a recycling process for plastics by making alkenes from a polymer and dehydrogenated polyethylene compositions.
