The theory of polymer melts is founded on the process of double reptation for high masses and long times, and on simple Rouse relaxation for low maases and short times. In order to describe the intermediate region, these two different principles have to be combined, and we show how this can be done. However, pure reptation is modified under the influence of an effect which cannot be reduced to the Rouse elasticity of polymers, and this effect could be calculated by mode‐mode coupling.
