| Abstract: | The data of an experimental investigation of polyester- and polyether-based elastomers are presented. The elastomers were investigated in creep while increasing the temperature in steps of 20°C. Infrared absorption spectra were obtained for a series of loads and temperatures and the variation of the total orientation of the molecular structure (birefringence) and the growth of the deformation with time were recorded. An attempt is made to interpret the changes in the rates of orientation of the molecular structure by varying the concentration of certain characteristic chemical bonds.Translated from Mekhanika Polimerov, No. 3, pp. 437–441, May–June, 1975. |
