CLAIMS

What is claimed is:

1. A biodegradable polyol comprising: a. a monomer of β-lactone derived from the carbonylation reaction of an epoxide with carbon monoxide, said epoxide having a bio-content greater than 10% and said carbon monoxide having a bio-content greater than 10%;b. wherein said monomer of β-lactone is polymerized with at least one monomer...

DESCRIPTION

FIELD OF THE INVENTION

The present invention is generally directed to environmentally responsible polyester polyol polymers, derivatives, and to the processes for producing the polyester polyol polymers and derivatives. Specifically, preferred polymerization processes include monomers comprised of carbons obtained from biological, recycled, renewable, or otherwise sustainable raw material sources. Advantageously, the unique characteristics of...
