  It is well known, that there is temporal relationship between CMEs and
associated flares. The duration of the acceleration phase is related to the
duration of the rise phase of a flare. We investigated CMEs associated with
long duration flares of slow rise phase (slow LDE). These CMEs are
characterized by high velocity (v>1000 km/s) during the propagation phase and
low average acceleration during the main, prolongated, acceleration phase. The
CMEs are accelerated until the height $> 5 R_\odot$, which is higher value than
in typical impulsive CMEs. CMEs associated with slow LDEs have characteristics
of both classes of CMEs, i.e. CMEs associated with flares and CMEs associated
with eruptive prominences.
