CHAIN FOLDING is one of several unexpected features of long‐chain polymer crystals that have come to light during the last decade or so. The polymers that exhibit these features are among our most important synthetic products—nylon and polyethylene, for example—and also abound in nature. The organization of their long‐chain molecules therefore has practical as well as fundamental significance. Along with the new discoveries we find simplifications that make certain phenomena more reproducible experimentally, as well as more amenable to theoretical treatment, in polymers than in simpler substances.
