## Abstract Plastic foam with nanoβ/microβscale cellular structures was prepared from a poly(propylene) (PP)/propyleneβethylene copolymer (PER) blend by controlling bubble nucleation sites and bubble growth in disperse PER domains. Batch foaming experiments using a CO~2~ pressure quench method were
