Abstract | A chemically modified plasticized starch (CMPS) is prepared by reacting starch with an organic dibasic acid or an anhydride of the acid in the presence of a plasticizer using optional free radical initiators, and optionally with the incorporation of nano clays in the reactive extrusion process. The starch is thermoplastic and has a lower viscosity than the traditional thermoplastic, starch. The CMPS is useful in preparing starch polymer compositions which are at least partially biodegradable.
Un amidon plastifié modifié chimiquement (CMPS) est préparé en faisant réagir l'amidon avec un acide organique dibasique ou un anhydride d'un tel acide, en présence d'un plastifiant, en utilisant des initiateurs à radicaux libres facultatifs, éventuellement avec incorporation de nano-argiles dans le processus d'extrusion du produit réagissant. L'amidon est thermoplastique et présente une viscosité plus faible que l'amidon thermoplastique de type courant. Le CMPS est utilisé pour la préparation de compositions polymères d'amidon qui sont au moins partiellement biodégradables |
