Title (EN) ABSORBENT POLYMERS, AND METHODS OF PRODUCING THEREOF AND USES THEREOF
(FR) POLYMÈRES ABSORBANTS, PROCÉDÉS DE PRODUCTION ET UTILISATIONS ASSOCIÉS
Abstract:
(EN) Provided herein are absorbent polymers produced from beta-propiolactone, and methods of producing such polymers. These absorbent polymer may be cross-linked. The beta-propiolactone may be derived from ethylene oxide and carbon monoxide. The absorbent polymer may be bio-based and/or bio-degradable. The absorbent polymers may be used for diapers, adult incontinence products, and feminine hygiene products, as well as for agricultural applications.
(FR) L'invention concerne des polymères absorbants produits à partir de bêta-propiolactone, ainsi que des procédés de production de ces polymères. Ces polymères absorbants peuvent être réticulés. La bêta-propiolactone peut être issue d'oxyde d'éthylène et de monoxyde de carbone. Le polymère absorbant selon l'invention peut être biosourcé et/ou biodégradable. Les polymères absorbants peuvent être utilisés dans des couches, des produits pour l'incontinence des adultes et des produits d'hygiène féminine, ainsi que dans des applications agricoles.
