Abstract
The resistance of poly (vinylidene fluoride)/poly (methyl methacrylate) (PVDF/PMMA) blends was investigated using the artificial aging and neutral salt spray tests. The solution of each polymer was prepared using the N, N-dimethylformamide (DMF) as a solvent for the two polymers. The PVDF/PMMA blend is a compromise of a great development in the field of architectural preservation, since it is the best method in term of quality and price to make new polymeric materials having enhanced properties. The addition of PVDF to PMMA enhances the properties of this last to know the exhibition in the natural and artificial ageing and to the saline fog. The results showed that the exposure of coatings to artificial aging and to the salt water vapors showed a high resistance of the blend at compositions ≥ 70 of PVDF/PMMA.
