Abstract
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.
