PHASE TRANSFORMATION. Vol. 10. PHASE TRANSFORMATION. Introduction. Phase transformations of polymeric materials, such as unmixing of a polymer solu-tion or polymer blend, or the crystallization of a polymer melt or its glass transition into an amorphous structure, are very common phenomena and have important applications.
