Birefringence in Rubbers [PDF]
Nature, 1950 IT has been shown, both theoretically1 and experimentally2,3, that in simple elongation of a sample of a pure gum vulcanizate, an approximately linear relationship between the tensile stress t and the birefringence (n1 − n2) obtains, provided the strain is not sufficiently large to produce crystallization. We may write
