摘要：

A solid-state mechanochemical processing,that is,pan-milling,was used to conduct the esterification of poly(vinyl alcohol) (PVA) with maleic anhydride (MA) through stress-induced reaction.FTIR spectrum study indicated the presence of ester linkages and olefinic double bonds in maleic anhydride cross-linked PVA.Thermal properties of the cross-linked product were characterized by DSC.The results showed its glass transition temperature was 20℃higher than the original linear PVA and the thermal stability was also improved.
