Abstract

The present invention is directed to biodegradable polyester polyol polymers having high bio-based content and methods for producing biodegradable polyester polyol polymers having high bio-based content. In preferred embodiments, beta-lactone monomers may be produced from epoxide and carbon monoxide having high bio-based content. In certain preferred embodiment, the beta-lactone is beta-propiolactone produced from ethylene oxide and carbon monoxide. In certain embodiments, beta-lactones may be polymerized with diols, triols, and polyols to form the biodegradable polyester polyol polymers having high bio-based content. In some embodiments, the biodegradable polyester polyol polymers having high bio-based content may be terpolymers formed from a first beta-lactone, a diol, triol, or polyol,and a second beta-lactone. In some other embodiments, the biodegradable polyester polyol polymers having high bio-based content may be copolymers formed from a polylactone oligomer and a diol, triol,or polyol.

Description

technical field [0001] The present invention relates generally to environmentally responsible polyester polyol polymers, derivatives, and to processes for producing polyester polyol polymers and derivatives. In particular, preferred polymerization processes include monomers composed of carbon obtained from biological, recycled, renewable or other sustainable feedstock sources. Advantageously, the unique properties of polyol polymers are well suited for environmentally responsible applications. Background technique [0002] For the purposes of this invention, the terms "biobased", "biobased content" and "biocontent" are used interchangeably to describe carbon atoms from biological sources, recycled sources, renewable sources and / or other sustainable sources . Due to unique physical and chemical properties, carbon atoms are the building blocks of many manufactured materials. An important use of carbon atoms is to make polymers. [0003] Typically, polymers are larger molec...
