Title
(EN) AQUEOUS BIOPOLYMER DISPERSIONS
(FR) DISPERSIONS AQUEUSES DE BIOPOLYMÈRES
Abstract
(EN) An aqueous biopolymer dispersion composition comprising: a biopolymer selected from the group consisting of: polybutylene adipate terephthalate (PBAT), polybutylene succinate (PBS), polybutylene succinate adipate (PBSA), polylactic acid (PLA), poly(3-hydroxybutyrate) (PHB), polycaprolactone (PCL), poly(3-hydroxybutyrate-co-3-hydroxyhexanoate) (PHBH); poly(3-hydroxybutyrate-co-3-hydroxyvalerate) (PHBV), polyhydroxyalkanoate (PHA), and mixtures thereof; a stabilising agent selected from the group consisting of: polyvinyl alcohol, fatty alcohol ethoxylates, ethylene oxide/propylene oxide (EO/PO) block copolymers, salts of fatty acids and mixtures thereof; a rheology modifier; a cross linking agent; optional further ingredients; and water.
(FR) L’invention concerne une composition de dispersion aqueuse de biopolymères comprenant : un biopolymère choisi dans le groupe constitué par : le poly(adipate et téréphtalate de butylène) (PBAT), le poly(succinate de butylène) (PBS), le poly(succinate et adipate de butylène) (PBSA), le poly(acide lactique) (PLA), le poly(3-hydroxybutyrate) (PHB), la polycaprolactone (PCL), le poly(3-hydroxybutyrate-co-3-hydroxyhexanoate) (PHBH) ; le poly(3-hydroxybutyrate-co-3-hydroxyvalérate) (PHBV), un polyhydroxyalcanoate (PHA) et leurs mélanges ; un agent stabilisant choisi dans le groupe constitué par : le poly(alcool vinylique), les produits d’éthoxylation d’alcools gras, les copolymères à blocs oxyde d’éthylène/oxyde de propylène (OE/OP), les sels d’acides gras et leurs mélanges ; un agent modifiant la rhéologie ; un agent de réticulation ; éventuellement des ingrédients supplémentaires et de l’eau.
