This scheme is used as application to random heteropolymer theory, whose Hamiltonian is found to be a free energy in dependence on a compositional order parameter. Here, instead of proper Langevin equation an effective one is proposed to describe alternation of different monomers along a polymer chain. Isothermal and adiabatic susceptibilities, as well as order parameter and irreversible response are determined as functions of temperature and quenched disorder.
