| Popis: | New polymer composites based on an unsaturated polyester matrix and magnetic pigmented filler were prepared and tested for their mechanical and magnetic properties. It was prepared by calcining iron oxide and alumina in the presence of molybdenum and its physical properties were investigated. Three different compositions of Fe2O3 and alumina Al(OH)3 namely 1:1, 2:1, and 1:2 of Fe2O3:Al2O3 were also prepared. The matrix consists of two unsaturated polyesters (modified and unmodified). The modified one was synthesized by the reaction of carboxyl-terminated unsaturated polyester with (polyethylene glycol) of molecular weight 400 g mol−1 to increase the solution behavior (solubility) in styrene. They were characterized by the IR, NMR spectrum, DSC, and GPC. The results obtained showed that, the prepared pigment compositions had moderate values of oil absorption, specific gravity, and bulking values and their pH concentration was in the alkaline range. The mechanical strength and also the magnetic properties o... |
