Title (EN) PROCESS FOR THE MANUFACTURE OF POLYCYCLOHEXANE DIMETHYLENE TEREPHTHALATE COPOLYMERS FROM POLYETHYLENE TEREPHTHALATE, AND COMPOSITIONS AND ARTICLES THEREOF
(FR) PROCÉDÉ DE FABRICATION DE COPOLYMÈRES DE POLYCYCLOHEXANE DIMÉTHYLÈNE TÉRÉPHTALATE À PARTIR DE POLY(TÉRÉPHTALATE D'ÉTHYLÈNE) ET COMPOSITIONS ET ARTICLES À BASE DE CES COPOLYMÈRES
Abstract:
(EN) A process comprises heating at a first temperature under an inert atmosphere and at a first pressure of at least 101 kPa a cyclohexanedimethanol, and a polyethylene terephthalate component selected from the group consisting of polyethylene terephthalate and polyethylene terephthalate copolymers, to form a molten mixture; and heating the molten mixture with agitation at a second temperature higher than the first temperature and a second, subatmospheric pressure for a time and under conditions effective to form a modified polycyclohexane dimethylene terephthalate copolymer comprising at least one residue derived from the polyethylene terephthalate component.
(FR) L'invention porte sur un procédé qui comporte les opérations consistant à chauffer, à une première température, dans une atmosphère inerte et à une première pression d'au moins 101 kPa, un cyclohexanediméthanol et un composant poly(téréphtalate d'éthylène) choisi dans le groupe constitué par le poly(téréphtalate d'éthylène) et les copolymères de poly(téréphtalate d'éthylène) afin de former un mélange fondu ; et à chauffer le mélange fondu avec agitation à une seconde température supérieure à la première température et à une seconde pression inférieure à la pression atmosphérique, pendant un laps de temps et dans des conditions efficaces pour former un copolymère de polycyclohexane diméthylène téréphtalate modifié renfermant au moins un reste issu du composant poly(téréphtalate d'éthylène).
