This paper describes experimental work where the mechanical behaviour of relatively dry, solid poly(acrylic acid) films at room temperature was correlated with changes in hydrogen‐bonding in the polymer. Hydrogen‐bonding between the carbonyl and the hydroxyl groups was followed by FT‐IR spectroscopy while the films were stretched uniaxially. Limited mobility of the polymer below its T g led to small but detectable changes in bonding. A characteristic strain‐hardening behaviour was observed if no bound water was detected in the samples.
