Solution dynamics of associating polymer chains with many 
randomly distributed strongly interacting groups (stickers) are
considered theoretically. The stickers tend to associate pairwise, and
the polymer backbone is semirigid and soluble. It is shown that
there exists a finite concentration range where the polymers form a
reversible network with a virtually frozen structure: in this regime
both the stress relaxation time and the viscosity exponentially
increase with N and with c.
