Abstract
(EN)
Esters of polylactic acid, including polyethylene glycol esters of polylactic acid, that are coupled with an acid are disclosed. Exemplary coupled esters of polylactic acid can be used as textile finishes. Methods of making the coupled esters of polylactic acid via direct and/or transesterification reactions are also disclosed.
(FR)
L'invention concerne des esters d'acide polylactique, y compris des esters d'acide polylactique de polyéthylène glycol, qui sont couplés à un acide. Les esters d'acide polylactique donnés à titre d'exemple peuvent être utilisés en tant qu'apprêts textiles. L'invention concerne également des procédés de préparation des esters d'acide polylactique couplés par l'intermédiaire de réactions directes et/ou de transestérification.
