摘要：
The paper is concerned with the conformational characteristics of polyacrylonitrile in dilute solutions. The observed dependences of the second virial coefficient, A(2), on the molecular weight, over a large domain of molecular weights, were quantitatively explained by the Yamakawa theory that takes into account the effects of chain ends and chain stiffness.
