Preparation and evaluation of the antibacterial alkyd resin modified with 2,2\ -di-thiosalicylic acid

El-Said H.El-Mosallamy, Mohamed Y.Gabr

This paper reported on the synthesis of a series of modified alkyd resins by partial replacement of phthalic anhydride with 2,2\-di-thiosalicylic acid. The modifier containing aromatic ring and sulphur atom which enhancing the physical, mechanical and chemical properties of the modified alkyds, especially at higher content. The antibacterial activitywas also investigated and gave promising results which promoted the application of the modified alkyds and in antibacterial aspects especially at high modifier content.
