Title
(EN) CHAIN EXTENSION OF POLYETHYLENE TEREPHTHALATE WITH POLYACYLLACTAMS
(FR) EXTENSION DE CHAINE DE POLYTEREPHTALATE D'ETHYLENE A L'AIDE DE POLYACYLLACTAMES
Abstract
(EN)
High molecular weight polyethylene terephthalate resins in which there is used a chain extending agent having formula (I), wherein A is any hydrocarbon group having the necessary number of available valences to bound itself to all of the acyl groups of the compound, y is at least 1 and x is an integer of from 6 to 12. Preferably, the chain extending agent is a bisacyllactam, such as terephthaloyl bislaurolactam. The chain extending agent can be used in combination with a carboxyl reactive compound.
(FR)
On a mis au point des résines de polytéréphthalate d'éthylène de poids moléculaire élevé, dans lequelles on utilise un agent d'extension de chaîne ayant la formule (I), dans laquelle A représente un groupe d'hydrocarbures ayant le nombre nécessaire de valences disponibles afin de se lier à tous les groupes acyle du composé. y représente au moins 1 et x est un nombre entier compris entre 6 et 12. L'agent d'extension de chaîne est de préférence un bisacyllactame, tel que le téréphtaloyle bislaurolactame. On peut utiliser l'agent d'extension de chaîne en combinaison avec un composé réactif de carboxyle.
