Abstract
Values of segmental optical anisotropy of macromolecules of vinyl acetate – vinyl alcohol copolymers are determined by the photoelasticity method. It is shown that in the range of 0,2 – 0,75 mole fraction of vinyl alcohol units, the dependence of segmental optical anisotropy of copolymers on their composition is essentially nonlinear. It is found that the transition of PVA conformation into PVAl conformation proceeds in the same composition range.
