It is commonly believed that a not yet detected active process has to be involved in this segregation. Recent analytical results obtained in the framework of the de Gennes blob model however show that entropy alone provides a strong segregating force for polymers in confinement. The timescale for the entropic segregation scales as $N^2$, which is much faster than the $N^3$ timescale of a pure diffusional segregation. We present results from MD simulations which confirm these predictions and give further insight into the segregation process.
