Phys. Rev. Lett. 73, 1602–1604 (1994)Random Copolymers with Short-Range Interaction in the Equilibrium State: Mean Field Approximation and Numerical StudiesReceived 8 April 1994; published in the issue dated 19 September 1994 We study macromolecules with quenched random charge disorder along the chain and short-range interactions between the monomers. Within a mean-field approach a collapse of a chain with increasing disorder is found, which becomes more pronounced for long chains. Molecular dynamics simulations reveal the same tendency, though the actual shape of the radius of gyration as a function of the disorder is different and reflects the finite length of a chain. © 1994 The American Physical Society URL:
