DescriptionThe aim of the present study was to combat wood decay based on the approach controlled-release biocides from polymers. The possibility of introducing polymer-bonded fungicides into the cell lumens was investigated. The synthesis of ethylene maleic anhydride copolymer containing pentachlorophenol (penta) and 8-hydroxy quinoline (8HQ) in N, N dimethyl formamide is described. It was demonstrated that the penta-bonded acrylate is a poly(ethylene co-dipentachlorophenyl diacrylate), which has a disubstituted pentachlorophenyl group linked through two acrylate ester bonds. The reaction of ethylene maleic anhydride copolymer with 8-hydroxy quinoline leads to products containing 44.8% poly(ethylene co-8-hydroxy quinolinyl acrylate) and 55.2% of unreacted poly(ethylene co-maleic anhydride). Wood impregnated with the polymers described prevented decay by a brown-and white-rot fungus, even after water leaching. Wood treated with the fungicide pentachlorophenol (penta) alone prevented only decay by a brown-rot fungus. An advantage is that high loading of penta in polymer can be achieved. Moreover, there is a slow-release effect on the active agent due to hydrolysis of ester bonds. The decay resistance of wood treated with poly(ethylene co8-quinolinyl acrylate) was similar to that of wood impregnated with 8-hydroxy quinoline.
