“…Such models can be extended in various ways, e.g., to include bending potentials, , attractive nonbonded interactions, or (in the case of polymer solutions) a hydrodynamic coupling to a fluid medium . They have been used to verify scaling predictions , and to study generic aspects of single polymer phase transitions such as chain adsorption or the coil–globule transition − properties of polymer melts and blends and even dynamical transitions such as the glass transition. − To some extent, they can also be used to make quantitative predictions for chemically specific polymers. For example, recent work by Everaers and co-workers has shown that, for a wide range of commodity polymer melts, matching a single local property in melts of Kremer-Grest chains, the so-called dimensionless Kuhn number, is sufficient to reproduce the correct entanglement modulus. , The Kuhn number is derived from microscopic quantities, i.e., the number of Kuhn segments in a volume of Kuhn length cube.…”
