Statistical segment model

The above equation has found high applicability by combining it with the relationship for the true stress, as derived from the Gaussian theory of rubber elasticity. Specifically this theory leads to 

In conjunction with the above equations it can be shown that if N n and bi — bz) are known, one can use birefringence to determine the average angle, (f), that a segment makes with the stretch axis. Specifically, to a good first approximation 

The above discussion has been only concerned with homopolymer
