The scaling behaviour of linear polymers in disordered media, modelled by self-avoiding random walks (SAWs) on the backbone of three- and four-dimensional percolation clusters is studied by Monte Carlo simulations. We apply the pruned-enriched Rosenbluth chain-growth method (PERM). Our numerical results bring about the estimates of critical exponents, which characterise disorder averages of end-to-end distance and number of SAWs.
