We have built a hydraulic mechanical stretcher to be used with a Fourier transform infrared spectrometer to monitor molecular response when polymer samples are deformed macroscopically. Experiments on ethylene-methacrylic acid copolymers and their neutralized forms have been carried out to demonstrate the potential usefulness of this type of experiments.
