The first non-centrosymmetric
lamellar systems were reported recently by Stadler et al.
They were obtained from ABC triblock and AC diblock copolymers
when they arrange in the sequence "ABCCAABCCA
”.
We give a tentative theoretical explanation
for such a superlattice arrangement
and obtain predictions for the phase diagram of such systems
in terms of the molecular parameters.
