“…Among the systems dealt with by soft-matter physics of prime importance are solutions and melts of block copolymers whose linear macromolecules consist of rather long blocks of single-type monomeric units [1,2]. A distinctive feature of the phase behavior of such systems is their ability to form spatially periodic mesophases with the periods lying in the nanometer scale [3,4].…”
The phase behavior of a melt of two-scale multiblock copolymers has been theoretically studied in the framework of the Weak Segregation Limit theory with a twocomponent order parameter. The existence of a thermodynamically stable mesophase with two scales of the space periodicity has been revealed for a melt of monodisperse nonperiodic heteropolymers. For the first time a discontinuous change with temperature of the spatial period of the mesophases has been predicted.

scite is a Brooklyn-based organization that helps researchers better discover and understand research articles through Smart Citations–citations that display the context of the citation and describe whether the article provides supporting or contrasting evidence. scite is used by students and researchers from around the world and is funded in part by the National Science Foundation and the National Institute on Drug Abuse of the National Institutes of Health.
