Title (EN) POLY(ACRYLIC ACID) FROM BIO-BASED ACRYLIC ACID AND ITS DERIVATIVES
(FR) POLY(ACIDE ACRYLIQUE) PRODUIT À PARTIR D'ACIDE ACRYLIQUE BIO-RESSOURCÉ ET SES DÉRIVÉS
Abstract:
(EN) Bio-based glacial acrylic acid, produced from hydroxypropionic acid, hydroxypropionic acid derivatives, or mixtures thereof and having impurities of hydroxypropionic acid, hydroxypropionic acid derivatives, or mixtures thereof, is polymerized to poly(acrylic acid) or superabsorbent polymer using the same processes as petroleum-derived glacial acrylic acid.
(FR) La présente invention concerne de l'acide acrylique glacial bio-ressourcé, produit à partir d'acide hydroxypropionique, de dérivés d'acide hydroxypropionique ou de leurs mélanges et ayant des impuretés d'acide hydroxypropionique, de dérivés d'acide hydroxypropionique, ou de leurs mélanges, qui est polymérisé en poly(acide acrylique) ou polymère superabsorbant en utilisant les mêmes procédés que l'acide acrylique glacial dérivé du pétrole.
