Abstract

The current study aimed at studying the mechanical and bioactivity properties of gypsumpolymer composites. Poly(vinyl alcohol) (PVA) and its copolymers with vinyl acetate and itaconic acid in addition to vinyl acetate and vinyl chloride. The mass percentage of each of these polymers in the prepared composites was pre-selected after optimization of their mechanical properties. Gypsum and polymers were mixed with DI H2O at a proper P/L ratio. Composites were soaked in simulated body fluid (SBF) for 2 weeks and, in another study, in SBF for a week, then another week in 1.5 SBF. Changes in Ca 2+ and PO4 3- ions, weight loss and morphology of the solid samples were monitored. Resorption of gypsum was observed with a concurrent deposition of apatite in all composites, including polymer-free gypsum. Despite these findings, composites did not lose their mechanical integrities, suggesting their stabilities when used as bone cements.
