Abstract
The bond fluctuation model on a square lattice with a bond‐length dependent potential exhibits in simulations of slow cooling a kinetic glass transition where the system falls out of equilibrium. Extending previous work, the relaxation functions of gyration radius and end‐to‐end distance, and the bond autocorrelation function of the polymers are presented and related to the time‐dependent displacements of inner monomeric units and center of gravity of the whole chains, respectively. Over a wide temperature range the data can be collapsed on master curves satisfying the time‐temperature superposition principle for Rouse dynamics.
