We report studies of spin dynamics in the conducting polymers
polyaniline and polypyrrole using both mu(+)SR and mu(-)SR techniques.
These measurements reveal characteristic held dependences and cutoff
frequencies for the muon spin relaxation which can be related to the
spin diffusion process. Clear evidence is seen for increased spin
localisation at low temperatures where a crossover occurs from two or
three dimensional spin diffusion to a one dimensional diffusion regime.
