Title
(EN) PARTIALLY ESTER-EXCHANGED SIPM AND PROCESS THEREWITH
(FR) SIPM PARTIELLEMENT ESTER-ECHANGE ET PROCEDE ASSOCIE
Abstract
(EN)
A process for producing a partially ester-exchanged SIPM such as an alkali metal bis(2-hydroxyethyl) 5-sulfoisophthalate produced from an alkali metal dimethyl 5-sulfoisophthalate in an alcohol is disclosed. The partially ester-exchanged SIPM in an alcohol can be used to copolymerize with oligomer of terephthalic acid or dimethyl terephthalate and an alcohol. Also disclosed is a process for controlling the color of a dyeable polyester using a phosphorous compound.
(FR)
L'invention concerne un procédé permettant de produire un SIPM partiellement ester-échangé, notamment un 5-sulfoisophthalate de bis(2-hydroxyéthyl) de métal alcalin, produit à partir d'un 5-sulfoisophthalate de diméthyle de métal alcalin dans un alcool. Ce SIPM partiellement ester-échangé d'un alcool, peut être utilisé pour une copolymérisation avec un oligomère d'acide téréphtalique ou un téréphthalate de diméthyle et un alcool. L'invention concerne également un procédé permettant de commander la couleur d'un polyester pouvant être coloré au moyen d'un composé phosphoreux.
