| description | A thin film composite polyamide membrane including a porous support and a thin film polyamide layer which is a reaction product of m-phenylene diamine (mPD) and trimesoyl chloride (TMC), wherein the membrane is characterized by the thin film polyamide layer having a dissociated carboxylic acid content of at least 0.18 moles/kg at pH 9.5, and wherein pyrolysis of the thin film polyamide layer at 650C results in a ratio of responses from a flame ionization detector for fragments produced at 212 m/z and 237 m/z of less than 2.8.
On décrit une membrane de polyamide composite à film mince comprenant un support poreux et une couche de polyamide en film mince, qui est un produit de réaction de diamine de m-phénylène (mPD) et de chlorure de trimésoyle (TMC). La membrane se caractérise en ce que la couche de polyamide en film mince présente une teneur en acide carboxylique dissociée d'au moins 0,18 moles/kg à un pH de 9,5. La pyrolyse de la couche de polyamide en film mince à 65°C indique un ratio de réponses issu d'un détecteur à ionisation de flamme pour des fragments obtenus à 212 m/z et 237 m/z, et inférieurs à 2,8. |
