Antibacterial Copolymer Synthesized from Methyl Methacrylate and 3-Pentachlorophenyloxy-1-propene
E-mail:
Methyl methacrylate (MMA) was copolymerized with either pentachlorophenyl acrylate (PCA) or 3-pentachlorophenyloxy-1-propene (POP) to obtain poly(MMA-co-PCA) and poly(MMA-co-POP), respectively. Pentachlorophenol (PCP) was linked to poly(MMA-co-PCA) via ester bond while it was linked to poly(MMA-co-POP) via ether bond which is usually more resistant to hydrolysis. Poly(MMA-co-POP) underwent glass transition at a lower temperature (88 ℃) than poly(MMA-co-PCA) (115 ℃) due to less content of ester bonds. However, poly(NMA-co-POP) underwent thermal degradation at a slightly higher temperature (329 ℃) than poly(MMA-co-PCA) (284 ℃) probably due to more stable POP unit compared to PCA unit. The inhibition zone test indicated that the two different polymers were not significantly different in their antibacterial activities and they were bactericidal or bacteriostatic, depending on the bacterial species used.
