Front Cover : In article number 2100442 by Richard J. Spontak and co‐workers, thermoplastic elastomers possessing polyethylene endblocks and a random‐copolymer midblock composed of styrene and ethyleneco‐ co ‐butylene undergo concurrent self‐assembly and crystallization from solution. The transmission electron microscopy image displayed here reveals an aggregate possessing unstained crystals, whereas the smallangle (top) and wide‐angle (bottom) X‐ray scattering profiles indicate the solution concentrations at which self‐assembly and crystallization, respectively, are first observed.
