  We consider rotating Primordial black holes (PBHs) and study the effect of
accretion of radiation in the radiation dominated era. The central part of our
analysis deals with the role of the angular momentum parameter on the evolution
of PBHs. We find that both the accretion rate and evaporation rate decrease
with increase in angular momentum parameter, but the rate of evaporation
decreases more rapidly than the rate of accretion. This shows that the
evaporation time of PBHs get prolonged with increase in angular momentum
parameter. We also note that the lifetime of rotating PBHs increase with
increase in accretion efficiency of the radiation as in the case of nonrotating
PBHs.
