The present invention relates to a composition comprising platelet particles treated with at least one polyalkoxylated ammonium salt comprising at least one polyalkoxylated group consisting of greater than 5 repeating alkyl oxide groups. The treated particles of the present invention display particularly good dispersion when incorporated into various polyester compositions at concentrations up to about 25 weight %. Also disclosed is a process incorporating said treated platelet particles into a polyester and for forming said treated platelet particles.
La présente invention concerne une composition comportant des particules lamellaires traitées au moyen d'au moins un sel d'ammonium polyalcoxylaté comprenant au moins un groupe polyalcoxylaté comportant des groupes répétitifs alkyloxyde supérieurs à 5. Les particules traitées de la présente invention se prêtent particulièrement bien à la dispersion lorsqu'elles sont incorporées dans diverses compositions de polyester à des concentrations pouvant atteindre 25 % de la masse. L'invention concerne également un procédé permettant l'incorporation desdites particules lamellaires traitées dans un polyester, et un procédé permettant de former lesdites particules lamellaires traitées.
