Abstract The IR-spectroscopic identification of soft rubbers may be made by : 1. Breaking down the vulcanizate on a mill followed by boiling with o-dichlorobenzene and then the spectroscopic examination of the polymer recovered from the solution. 2. Thermal degradation of the vulcanizates followed by spectroscopic examination of the liquid and gaseous products of pyrolysis. The rubber base of hard rubbers is determined by spectroscopic examination of the materials obtained by thermal degradation of mixtures of the hard rubbers with zinc dust or powdered calcium.

Infrared spectroscopic investigations have shown that on the basis of changes in the ν3, SO4 band which occur when calcium sulphate is heated from 400° to 1400 °C, there are two forms of insoluble anhydrite, designated as β′- and β-CaSO4. β′-CaSO4 is metastable and is completely converted into β-CaSO4 by heating above 1000 °C. With longer heating periods this conversion can even take place at lower temperatures. β-CaSO4 is stable and is of the same type as the naturally occurring form of anhydrite.
