  We present a theoretical framework for the linear and nonlinear visco-elastic
properties of reversibly crosslinked networks of semiflexible polymers. In
contrast to affine models where network strain couples to the polymer
end-to-end distance, in our model strain rather serves to locally distort the
network structure. This induces bending modes in the polymer filaments, the
properties of wich are slaved to the surrounding network structure.
Specifically, we investigate the frequency-dependent linear rheology, in
particular in combination with crosslink binding/unbinding processes. We also
develop schematic extensions to describe the nonlinear response during creep
measurements as well as during constant-strainrate ramps.
