Abstract : Crude rubber becomes double refracting during storage. Longitudinal elongation leads to positive biaxial double refraction. The determination is unambiguous if it is possible to perform the observations in the direction of the stretching. In the case of vulcanized rubber only positive uniaxial or biaxial double refraction can be considered. The lamellar deformation leads in all cases to weak negative biaxial double refraction.
