Ionic binding is affected in pressure‐sensitive acrylate‐based copolymers containing carboxylic groups by introduction of Na ions. The tack and peel force of pressuresensitive polymers decreased and the resistance to creep increased with increasing degree of ionic binding. An infrared spectroscopic method for the assay of sodium content has been developed based on the ratio of absorbances at 5.75 and 6.28 μ due to ester carboxyl and ionized carboxyl, respectively.
