A NONEQUILIBRIUM APPROACH FOR RANDOM AMPHIPHILIC COPOLYMER MODEL

We propose a self-consistent method for studying equilibrium and kinet ics of a random copolymer model with a Gaussian distribution of quench ed disorder characterized by a generic covariance matrix. The complete phase diagram of the model is obtained and it contains five different states separated by the collapse, glass, and folding ''transitions.'' We analyze the thermodynamic limit for the high-density collapsed glo bule that permits a simplified analytical study. We argue that the app roach may be applied in a variety of situations including biopolymers, gels, and other soft random materials.
