Stress‐temperature relations at constant elongation and at constant length have been studied
in a pure‐gum vulcanizate of GR‐S. Such studies yield information useful for calculations …

… According to the present work in the case of natural rubber, either unvulcanized or in our
pure-gum vulcanizate, this range of validity is found to be reduced to zero. We suggest the …

… Stress-temperature relations at constant elongation have been investigated for a pure-gum
vulcanizate of natural rubber. The rubber was first allowed to relax for about two hours at …
