Title
(EN) SULPHUR-CONTAINING POLYESTER
(FR) POLYESTER CONTENANT DU SOUFRE
Abstract
(EN)
The present invention relates to a sulphur-containing polyester obtainable by a process comprising esterification reactions between a polyol and a carboxylic acid and a thiolactic acid, or by a process comprising an esterification reaction between a partially esterified polyol and a thiolactic acid. It also concerns its use as a multiproperty additive, and compositions comprising it.
(FR)
La présente invention concerne un polyester contenant du soufre pouvant être obtenu par un procédé comprenant des réactions d'estérification entre un polyol et un acide carboxylique et un acide thiolactique ou par un procédé comprenant une réaction d'estérification entre un polyol partiellement estérifié et un acide thiolactique. Elle concerne également son utilisation en tant qu'additif multipropriétés et des compositions le comprenant.
