The main assumptions and concepts used in molecular modelling of melt rheology are briefly reviewed. Because rheological phenomena take place over time scales which correspond to motions of large segments of the chains, models need only account for the long‐range structural aspects of the chain, while the local details of the chemical structure get lumped into a few adjustable parameters. The structural aspects which must be accounted for in a direct way are discussed, and a concise overview of the corresponding modelling is made.
