Disclosed are compositions, systems and methods related to a polypropiolactone composition comprising polypropiolactone polymers. Such polymers include polypropiolactone chains of Formula (I): where n is an integer from 10 to about 1,000 and Y is either —H or a cation.

Systems and processes for polymer production

Processes for producing alcohols from biomass are provided. The processes utilize supercritical methanol to depolymerize biomass with subsequent conversion to a mixture of alcohols. In particular the disclosure relates to continuous processes which produce high yields of alcohols through recycling gases and further employ dual reactor configurations which improve overall alcohol yields. Processes for producing higher ethers and olefins from the so-formed alcohols, through alcohol coupling and subsequent dehydration are also provided. The resulting distillate range ethers and olefins are useful as components in liquid fuels, such as diesel and jet fuel.

Processes for producing alcohols from biomass and further products derived therefrom

Provided are integrated processes for the conversion of ethylene oxide to polypropiolactone. System for the production of polypropiolactone are also provided.

Process and system for production of polypropiolactone

Provided are processes for monitoring and maintaining continuous carbonylation of epoxides or lactones. Processes include measuring parameters affecting the rate of the carbonylation reaction and adding supplemental replacement catalyst replacement components to maintain a constant rate of carbonylation.

Continuous carbonylation processes

Disclosed are compositions, systems and methods related to a polypropiolactone composition comprising polypropiolactone polymers. Such polymers include polypropiolactone chains of Formula (I): [Formula should be inserted here] where n is an integer from 10 to about 1,000 and Y is either &#x2014;H or a cation. 

Provided are integrated processes for the conversion of ethylene oxide to polypropiolactone. Systems for the production of polypropiolactone are also provided.

Provided are integrated processes for the conversion of beta propiolactone to acrylic acid. Systems for the production of acrylic acid are also provided.
