We investigate the dynamics of polymers whose solution configurations
are represented by fractional Brownian walks. The calculation of the t
wo dynamical quantities considered here, the longest relaxation time t
au(r) and the intrinsic viscosity [eta], is formulated in terms of Lan
gevin equations and is carried out within the continuum approach devel
oped in an earlier paper. Our results for tau(r) and [eta] reproduce k
nown scaling relations and provide reasonable numerical estimates of s
caling amplitudes. The possible relevance of the work to the study of
globular proteins and other compact polymeric phases is discussed.
