The effects in the infrared spectroscopy exam showed that PVA was esterified with stearic acid, and -OOC(CH2)16CH3 was introduced in to the aspect chain of PVA; the outcome with the water resistance test showed the water resistance of PVA enhanced with time. Huang et al. [sixty] organized esterified PVA films by the movement casting approach working with PVA and maleic anhydride as Uncooked products. The tensile properties and water resistance of PVA films had been also examined. The outcome confirmed which the tensile toughness of the esterified PVA film was significantly improved, as well as the tensile energy greater to forty nine.
