The evolution of the mean chain length 
and mean end to
end square radius 
of a two
dimensional system of living polymers at constant monomer concentration is studied as a
function of the obstacle density ρ. The fact that the system adapts the mean chain length
in order to reduce the entropic constraint does not lead to a different asymptotic dependence of
on ρ than what is observed for dead polymers. The change of the molecular weight
distribution form in the presence of obstacles suggests that a Levy flight could appear in
system of wormlike micelles in a porous medium.
