Theory of self-assembly of triblock ter-polymers in selective solvent towards corona-compartmentalized (Janus) micelles

We present a scaling theory of self-assembly of triblock ter-polymer ABC in selective solvent which is good or theta for both terminal blocks A and C, but poor for the middle block B. It is demonstrated that depending on the level of incompatibility between blocks A and C of the ter-polymer, equilibrium micelle has either laterally homogeneous (mixed) or segregated (“Janus”) corona.
