True-spherical PVC particles in the submicron-to-micron range fill a long-standing gap in the microplastic reference materials market — commercial PVC microspheres are typically produced by grinding, yielding irregular fragments that fail to mimic real environmental microplastic morphology.\u003c\/p\u003e\n\u003cp\u003eEach batch retains the characteristic chemical structure of PVC (FTIR C–Cl stretching band at 600–700 cm⁻¹) and is verified by FT-IR, SEM, and DLS.
