✦ Synopsis

In the light of recent fiuorcsccncc depolarization and nuclear magnetic resonance measurements in solutions of linear polymeric chain molecules, it is proposed that the local conformational changes belong to two main classes which do and do not obey the diffusion limit, respectively. The implications for internal viscosity effects on flow birefringencc and high frequency viscoelastic behnviour arc discussed.

Recent

developments of the dynamics of linear polymeric chain molecules relate [I] the coilective deformational modes (Rouse modes [2] ) to local CORformational changes. The local movements can be
