Copolymers of p-acryloyloxyacetophenone (AcAP) with MMA: Synthesis, Characterization and their Antifouling (AF) Efficiency

AcDP and AcAP were prepared by the reaction of acryloyl chloride (Ac) with 2,4,4' -trichloro-2' -hydroxydiphenyl ether (DP) and p-hydroxyacetophenone respectively in presence of triethylamine (TEA) in MEK at $0^{\circ}C$. The reaction was monitored by TLC and the prepared monomer was characterized by UV, IR, $1^H-NMR$ and GC-MS. Further, copolymers poly (AcDP-MMA-AcAP) were prepared in different feed ratio of monomers by free radical polymerization at $70^{\circ}C$, in which BPO as initiator and their molecular weight was determined by GPC. The AF activity of prepared polymers was investigated against representatives of marine microfoulers, shipfouling bacteria (B. macroides & P. aeruginosa) and microalgae (A.coffeaeformis & N. incerta). The antibacterial activity and diatom attachment assays showed significant AF potential of these polymers.
