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