Title (EN) PROCESS FOR ADDING FURYL-2-METHYLIDENE UV LIGHT ABSORBERS TO POLY(ETHYLENE TEREPHTHALATE)
(FR) PROCEDE D'ADDITION D'ABSORBANTS DE LUMIERE UV DE FURYLE-2-METHYLIDENE A UN POLY(ETHYLENE TEREPHTALATE)
Abstract: front page image
(EN)A method for incorporating a UV light absorbing compound into a polyester prepared using direct esterification of reactants selected from a dicarboxylic acid and a diol, the method comprising reacting the reactants in an esterifying reactor under conditions sufficient to form an esterified product including at least one of an ester, an oligomer, or mixture having an ester and a mixture of low molecular weight polyester; polymerizing the esterified product in a polycondensation reactor to form a polyester; and adding the UV absorbing compound to the esterified products when at least 50% of the carboxy groups initially present in the reactants have been esterified to obtain a yield of UV absorbing compound incorporated into the polyester of greater than 40%. Articles utilizing the UV protected polyester are additionally disclosed.
(FR)Il est prEvu un procEdE d'intEgration d'un composE absorbant la lumiEre UV dans un polyester fabriquE par estErification directe de rEactifs sElectionnEs parmi un acide dicarboxylique et un diol, le procEdE consistant A mettre en rEaction les rEactifs dans un rEacteur d'estErification dans des conditions suffisantes pour former un produit estErifiE comportant au moins un ElEment parmi un ester, un oligomEre ou bien un mElange comportant un ester et un mElange de polyester de faible poids molEculaire ; A polymEriser le produit estErifiE dans un rEacteur de polycondensation pour former un polyester ; et A ajouter le composE absorbant les UV aux produits estErifiEs lorsque l'on a estErifiE au moins 50 % des groupes carboxy initialement prEsents dans les rEactifs, pour obtenir un rendement de composE absorbant les UV incorporE au polyester de plus de 40%. Il est Egalement prEvu des articles utilisant le polyester protEgE contre les UV.
