| Abstract: | Polyvinyl alcohol (PVA) is a kind of linear polymer with a lot of hydroxyl groups and hydrogen bond, regular molecular structures, high crystallinity and high melt temperature(230℃ ). The PVA was modified with compound plasticizer and stabilizer. The influencing effects of modifiers on the molding performance of modified PVA were tested by using of DSC and FTIR. The results showed that the thermoplastics molding property of PVA was well improved by adding proper modifiers. |
