Title (EN) POLYESTER-WAX COMPOSITIONS AND METHODS OF MAKING THE SAME
(FR) COMPOSITIONS DE CIRE ET DE POLYESTER ET PROCEDES SERVANT A LES PREPARER
Abstract: front page image
(EN)The present invention relates to polyester compositions. More particularly, the present invention relates to polyester compositions comprising a) at least one polyester, and b) at least one wax, with the proviso that the composition contains less than about 50 ppm alkali or alkaline earth metal ions. Preferred waxes are oxidized polyethylene or maleated polypropylene waxes. Polyethylene terephthalate compositions containing for example only 20 ppm of these waxes display an improved crystallization behavior from the glass. Still further the invention relates to methods of making such polyester compositions.
(FR)L'invention concerne des compositions de polyester. Elle concerne, plus particulièrement, des compositions de polyester contenant a) au moins un polyester et b) au moins une cire, à condition que cette composition contienne moins de 50 ppm d'ions alcalins ou d'ions de métaux terreux alcalins. Les cires préférées consistent en des cires de polyéthylène oxydé ou de polypropylène maléaté. Des compositions de polyéthylène théréphtalate contenant par exemple uniquement 20 ppm de ces cires présentent une amélioration de leur comportement de cristallisation depuis l'état vitreux. L'invention concerne également des procédés de préparation de ces compositions de polyester.
