N2 - Using kinetic Monte Carlo simulations, an attempt was made to study how polymer sequence influences the dynamics of polymers in quenched disordered media. It was found that above a threshold temperature, polymers bearing monomers that are attracted to sites comprising the medium are more mobile than those which exhibit repulsive or neutral interactions. It was clarified that this effect originates from the fact that attractive interactions alleviate the entropic barrier of entering a narrow pore connecting neighboring void spaces in the disordered medium.
