Poly (sodium vinyloxyacetate) (PVOA) was prepared and the biodegradation was studied to develop a poly-vinyl-type biodegradable polyelectrolyte. PVOA may be converted readily to biodegradable poly (vinyl alcohol) by ordinary microbial reactions such as hydrolytic splitting of the pendant oxyacetic acid group. PVOA was found to be biodegraded by many microbial strains in soil and activated sludge obtained from a municipal sewage plant. <I>Bacillus cereus</I> LC, <I>Agrobacterium</I> sp. SC, <I>Cellulomonas</I> sp. Y1C and Y2C, <I>Aeromonas</I> sp. WC, <I>Pseudomonas</I> sp. T10 as bacterial strains and <I>Trichosporon cutaneum</I> RC as a yeast strain were isolated as PVOA-degrading strains. Copolymers containing vinyloxyacetate units showed improved biodegradability, suggesting the vinyloxyacetate unit to be useful as a biodegrading unit in copolymers.
