Coumarin, 3-phenyl, and 3-phenoxy coumarin polymers were prepared by the Perkin reaction of p-xylylene dichloride-salicylaldehyde polymer with acetic anhydride, phenyl acetic acid, and phenoxyacetic acid, respectively. The xanthone polymers were prepared by the Kostanecki reaction on p-xylylene dibromide-salicylic acid polymer with phenol or resorcinol. The flavone polymer were synthesized via chalcone intermediate from p-xylylene dichloride-o-hydroxyacetophenone polymer and benzalde-hyde. All the coumarin, xanthone, and flavone polymer samples were characterized by elemental analyses, by IR spectral studies, by TGA, and by studying their antifungal activities.
