A number of new resins were synthesized from 2,4-dihydroxyacetophenone and 2,5-dihydroxyacetophenone by reaction with substituted hydroxy, amino, and chloro compounds and formaldehyde in presence of various acids and bases as catalyst. The resins were characterized by IR spectra. The solution and chemical properties of the resins were investigated. The solubility parameter was calculated from Small's and Hoy's group contribution methods. The fungicidal properties of the resins synthesized have been evaluated.
