Self-avoiding polymer chains trapped in annealed random media have been investigated by Monte Carlo methods. It is found that the configurational characteristics of a polymer are not affected by the media and are independent of the concentration of the impurities. This is in agreement with an early conjecture, but in disagreement with recent analytical results.
