We studied the anomalous behavior of resistivity and magnetoresistance (MR) of polyacetylene (PA) heavily doped with ClO4-, FeCl 4- and iodine at magnetic fields H=0-30 T in the temperature range 500 mK - 300 K. We attributed these anomalies to the low temperature saturation of electron dephasing by two-level systems of a special type (at low H). We demonstrate that the linear negative MR observed at high H indicates that a network of point interfibrillar contacts controls the current transport even in heavily doped PA.
