Abstract
Phase transformations in high polymers are reviewed broadly and with the purpose of high-lighting the similarities and dissimilarities between behavior in high polymers and in metals. Emphasis is placed upon the kinetic restraints that make phase transformations in high polymers sluggish for the most part, and upon the molecular factors that underlie them. The review deals specifically with transformations of four kinds : a) transformations between crystallographic polymorphs, b) transformations that accompany deformation, c) phase separations reminiscent of spinodal decomposition, and d) crystallization. In the last example, a discussion of polymer chain folding is given in simple physical terms.
