Abstract

Surface of aluminium oxide was modified using the adsorption of stearic acid molecules from benzene solution. The adsorption isotherm and the sedimentation properties of the aluminium oxide in the organic medium were determined. Commercial unsaturated polyester was cured to a cross‐linked structure using styrene, methyl methacrylate and methyl acrylate monomers as cross‐linking agents, and small amounts of peroxidic initiator to initiate the curing process. Different composite materials of polyester‐modified surface aluminium oxide were prepared, and the physicomechanical properties of the prepared composites were measured for the products in the form of cast laminates and rods.
