Abstract

It has recently been observed that a diblock copolymer melt can undergo a second microphase separation with increasing temperature. We use an equation-of-state description along with the random phase approximation to study the stability of the disordered system, and calculate the lower critical ordering temperature as a function of the polymer interaction parameters, chain lengths, and volume fractions.
