We study phase synchronization effects in a chain of nonidentical chaotic oscillators with a type-I intermit-
tent behavior. Two types of parameter distribution, linear and random, are considered. The typical phenomena
are the onset and existence of global all-to-all and cluster partial synchronization with increase of coupling.
Increase of coupling strength can also lead to desynchronization phenomena, i.e., global or cluster synchroni-
zation is changed into a regime where synchronization is intermittent with incoherent states. Then a regime of
