Conventional polymers contain various chemical, geometrical, and stereo-optical sequence irregularities along the backbone chain, which can be treated as noncrystallizable comonomers in statistical copolymers. For statistical copolymers, the link between chemistry (copolymerization to characterize statistical copolymers) and physics (crystallization to determine structures and properties) has recently been enhanced. This review discusses how the crystallization behavior and resulting semicrystalline structure of statistical copolymers are affected by the various microstructure parameters of their comonomers, such as content, distribution along or even among polymer chains, and size (determining their inclusion in or exclusion from the crystallites). The discussion of crystallization is focused on its interplay with component segregation at three different length scales: monomer, monomer sequence, and macromolecule. The first two mainly occur in homogeneous copolymers, whereas the last one is only operative for heterogeneous copolymers. In addition, some unique phenomena such as strong memory effects and (cross)fractionation are discussed briefly.
