Composites consisting of polypropylene matrix/ethylene-propylene elastomer/calcium carbonate filler assume two phase structures: 1, elastomer and filler particles are dispersed separately; 2, elastomer encapsulates filler particles. Formation of these phase structures can be extensively promoted by adding functionalized polypropylene or functionalized elastomer to the composites. The former materials, with good adhesion at the matrix/filler interface, have noticeably higher stiffness and yield stress, while the latter ones are characterized by higher tensile impact strength and extensibility. The effects of maleic anhydride or acrylic acid used for functionalization on the phase structure and mechanical properties of the ternary composites are very similar at the concentration used.
