Segmented polyurethane (SPU)/poly(vinyl chloride) (PVC) blends were particulated with γ‐Fe 2 O 3 . Interfacial properties of the composite were studied through the adsorption behaviors of SPU and PVC and their blends on γ‐Fe 2 O 3 particles surface. Mechanical properties of the composite were measured with dynamic mechanical analysis and tensile test measurements. PVC with functional groups (FPVC), because of strong interactions, showed preferential adsorption on γ‐Fe 2 O 3 compared with SPU and PVC. Moreover, the γ‐Fe 2 O 3 particles were covered by FPVC in the γ‐Fe 2 O 3 /SPU/FPVC composite. The adsorption layer of FPVC protected SPU from catalytic degradation by γ‐Fe 2 O 3 , resulting in increasing hydrolytic stability for SPU. © 2001 John Wiley & Sons, Inc.
