Abstract
(EN)
Provided is a gas barrier polymer provided by thermosetting a mixture comprising a polycarboxylic acid and a polyamine compound. With reference to the infrared absorption spectrum of the gas barrier polymer, the gas barrier polymer has an R, defined by formula (1), of greater than 1, wherein, using the straight line that connects the measurement point at 1493 cm-1 with the measurement point at 1780 cm-1 as the base line, I(1660) is the absorption intensity at 1660 cm-1 and I(1625) is the absorption intensity at 1625 cm-1. R = I(1660)/I(1625) - {-0.65 × (total amine/COOH) + 0.4225} (1)
(FR)
L'invention concerne un polymère barrière aux gaz obtenu par thermodurcissement d'un mélange comprenant un acide polycarboxylique et un composé polyamine. Si on se réfère au spectre d'absorption infrarouge du polymère barrière aux gaz, le polymère barrière aux gaz a un R, défini par la formule (1), supérieur à 1, I(1660) étant l'intensité d'absorption à 1660 cm-1 et I(1625) étant l'intensité d'absorption à 1625 cm-1, si on utilise la ligne droite qui relie le point de mesure à 1493 cm-1 avec le point de mesure à 1780 cm-1 comme ligne de base. R = I(1660)/I(1625) - {-0,65 × (amine totale/COOH) + 0,4225} (1)
