Title (EN) VINYL ENDS MEASURING METHOD
(FR) PROCÉDÉ DE MESURE D'EXTRÉMITÉS VINYLE
Abstract: front page image
(EN)A method for the measurement of vinyl ends concentration in a polyester polymer by dissolving the polymer in a liquid solution with fluorinated carboxylic acid or fluorinated carboxylic anhydride, optionally heating the liquid solution or the mixture to a temperature between about 30 °C and 300 °C, subjecting the resulting mixture to an analysis where a quantitative signal for a fluorine atom or a fluorine-containing compound is produced, and calculating the quantity or concentration of vinyl ends from said quantitative signals.
(FR)L'invention concerne un procédé pour la mesure de la concentration d'extrémités vinyle dans un polymère polyester par dissolution du polymère dans une solution liquide avec un acide carboxylique fluoré ou un anhydride carboxylique fluoré, chauffage éventuel de la solution liquide ou du mélange jusqu'à une température comprise entre environ 30 °C et 300 °C, soumission du mélange obtenu à une analyse qui produit un signal quantitatif pour un atome de fluor ou un composé contenant du fluor, et calcul de la quantité ou de la concentration d'extrémités vinyle à partir desdits signaux quantitatifs.
