| Popis: | A precursor rubber-toughened polymethyl-methacrylate (PMMA) powder developed by ball-milling was incorporated into a series of test bone cements, with different combinations of PMMA powder, rubber-toughened PMMA powder, MMA monomer and benzoyl peroxide (BPO) initiator. The resulting microstructures were characterized by electron microscopy and measurements made of the tensile properties, fracture mechanics parameters and curing features. It is demonstrated that rubber-toughened PMMA powder additions give a significant increase in elongation and fracture toughness, with a reduction in setting time. |
