Contents: Recent modifications of the Rouse theory for polymer melts and concentrated solutions are presented and compared with measurements of dynamic modulus and oscillatory first normal stress coefficients for cis-1,4-polybutadiene (PB). Measurements of finite-amplitude storage modulus and second normal stress coefficient are given alongside with current theories aimed to explain these effects. Nonlinear transient measurements for PB melts, although in some cases impeded by instrument compliance, provide critical test for theory. The procedure of extending results of the network theory to nonlinear behaviour, as exemplified by Carreau's model is shortly reviewed. It can be concluded that molecular theories based on clear, independently testable assumptions of molecular architecture, are likely to be better guides for progress in polymer dynamics, than empirical theories.
