✦ Synopsis

Far-infrared spectra of alkali metal salts of sulphonated poly(ethylene terephthalate) have been measured in the 575-75 cm ~ region. For each polymeric salt, an intense and broad absorption band, the frequency of which is cation mass dependent, has been observed and assigned to cation-motion in the electrostatic field of the anionic sulphonate groups. The results indicate the presence in this ionic polymer of cations in several different environments and/or the formation of ionic group associates of a multiplet or a low-order cluster type.

AMtraet--The glass transition temperatures of alkali metal salts of sulphonated poly(ethylene terephthalate) were found for the range of sulphonation from 1.9 to 10.1 mol%. It was found that T. depends largely on the degree of sulphonation rather than on the detailed properties of the cation. T~ae r

## Abstract The far infrared spectra of poly(L‐proline) I (190–35 cm^−1^) and II (400–35 cm^−1^) were obtained in the solid state at both 300° and 110°K. A significant difference in the region below 100 cm^−1^ was observed. A very intense band located at 60 cm^−1^ in the infrared spectrum of form I
