英文摘要	Due to the wide application of pva acetals, the biodegradation of pva modified by formaldehyde, n-butyraldehyde, glyoxaldehyde and glutaraldehyde was conducted in an intensive biodegradation environment. spectrophotometric analysis and weight loss were used to determine the biodegradation of pva, and the changes of the mechanical properties of pva acetals were also studied. an obvious decrease in biodegradation levels of all the modified samples was found, and a decrease in biodegradation level with increasing degree of acetals of pva. the biodegradation of poly(vinyl formal) is better than poly(vinyl butyral) with the same degree of acetals whereas the biodegradation levels of poly(vinyl glyoxal) are lower than poly(vinyl glutaral) which has the same degree of crosslinking. the difference between the ft-ir of the samples before and after biodegradation indicated scission of residual pva chain during the process.
