Abstract
A gas barrier polymer is formed by heat-curing a mixture including polycarboxylic acid and a polyamine compound, in which, in an infrared absorption spectrum, when a straight line connecting a measurement point at 1493 cmand a measurement point at 1780 cmis set as a baseline, an absorption intensity at 1660 cmis set as I(1660), and an absorption intensity at 1625 cmis set as I(1625), R represented by Equation (1) is greater than 1.R=I(1660)/I(1625)−{−0.65×(total amine/COOH)+0.4225}  (1)
