The microphase separation transition for asymmetric triblock and (A-B) m star copolymer melts is investigated following a mean-field approach proposed by Leibler for diblock copolymer melts. Continuous transitions are found in all triblock architectures and in stars for any m at some composition fc. The phase diagram for the equilibrium morphologies is notably altered by varying the architecture of triblock copolymers.
