Accelerated biodegradation of poly(vinyl alcohol) by a glycosidation of the hydroxyl groups

Biodegradability of N-acetyl- d-glucosamine (GlcNAc)-substituted poly(vinyl alcohol) (PVA) ( 1) in a soil suspension (pH 6.5) was investigated at 25°C for 40 days. Biochemical oxygen demand (BOD) of 1 with degree of substitution of 0.2–0.3 (DP=430–480) was higher than that of PVA under the degradati...

Summary:Biodegradability of N-acetyl- d-glucosamine (GlcNAc)-substituted poly(vinyl alcohol) (PVA) ( 1) in a soil suspension (pH 6.5) was investigated at 25°C for 40 days. Biochemical oxygen demand (BOD) of 1 with degree of substitution of 0.2–0.3 (DP=430–480) was higher than that of PVA under the degradation condition. Size exclusion chromatography (SEC), 1H NMR, and FT-IR measurements of the recovered sample indicated that biodegradation of PVA main chain was accelerated by partial glycosidation of hydroxyl groups in PVA.
