In this article, sulfonated ethylene‐propylene‐diene monomer terpolymer (H–SEPDM) was used to treat CaCO 3 particles. CaCO 3 particles are encapsulated by H–SEPDM through the reaction of sulfonic acid group (SO 3 H) in H–SEPDM with CaCO 3 to improve the interface adhesion of CaCO 3 with HDPE. In case the treated CaCO 3 is blended with HDPE, a brittle–ductile transition occurs. The impact strength of the blend rises sharply at 25–30 wt % CaCO 3 , and amounts to more than 700 J/m, four times as high as that of HDPE at 30 wt % CaCO 3 , without much loss of its yield strength and modulus. © 2001 John Wiley & Sons, Inc.
