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

Described herein are methods for the production of oligosaccharides, including functionalized oligosaccharides, from one or more sugars, such as one or more monosaccharides, using polymeric and solid-supported catalysts containing acidic and ionic groups. Also provided are the oligosaccharide compositions, including functionalized oligosaccharide compositions, obtained using the methods.

Oligosaccharide compositions and methods for producing thereof

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

Disclosed are methods for treating an ethylene oxide stream suitable for use in carbonylation reactions. Such treatment uses an inorganic solid to remove water from the ethylene oxide stream. Discloses are also systems to carry out the methods herein.

Methods and systems for treatment of ethylene oxide

Provided herein are absorbent polymers produced from beta-propiolactone, and methods and systems of producing such polymers. The beta-propiolactone may be derived from ethylene oxide and carbon monoxide. The absorbent polymer may be bio-based and/or biodegradable. The absorbent polymers may be used for diapers, adult incontinence products, and feminine hygiene products, as well as for agricultural applications.

Absorbent polymers, and methods and systems of producing thereof and uses thereof

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

The present invention is directed to compositions which may undergo thermolysis to produce a higher purity acrylic acid product. In preferred embodiments of the present invention, the compositions comprise polypropiolactone and one or more active salts. The one or more active salts may catalyze thermolysis of the polypropiolactone so that the polymer depolymerizes into acrylic acid monomers. Certain concentrations of the one or more active salts result in higher purity acrylic acid products of thermolysis. In certain preferred embodiments, the one or more active salts include an acrylate group which may decompose under thermolysis to provide acrylic acid and thus decrease the concentration of undesirable contaminants in the acrylic acid product. In certain preferred embodiment, the one or more active salts comprise sodium acrylate.

Compositions for improved production of acrylic acid

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.

Process for production of acrylic acid

Reactor systems and processes produce organic acids through thermolysis of polylactones. The reactor systems and processes introduce at least one epoxide reagent and carbon monoxide reagent to at least one reaction vessel through at least one feed stream inlet. The epoxide reagent and carbon monoxide reagent contact at least one carbonylation catalyst to produce at least one beta-lactone intermediate. The beta-lactone intermediate is polymerized with at least one initiator in the presence of a metal cation to produce at least one polylactone product. The polylactone product is heated under thermolysis conditions to produce at least one organic acid product. The processes control the presence of contaminates, impurities, catalytic materials, and/or reagents to provide for highly pure organic acid products.
