The temperature dependence of the correlation length of composition fluctuations and single chain statics and dynamics is studied in a symmetric, binary polymer blend. Our Monte Carlo simulation reveals a pronounced shrinking of the chain in the minority phase at low temperatures. However, only a weak temperature dependence of the single chain properties is found above criticality. Especially there is only a weak coupling between the correlation length of composition fluctuations and the relaxation of the internal chain structure. The coherent dynamic structure factor does not show any signs of a spatial restricted motion for our chain length N = 16, which is far below the entanglement length.
