| Abstract: | Michael addition reaction between poly (vinyl alcohol) (PVA) and propyl vinyl sulfoxide (PrVSO) was studied in sodium hydroxide aqueous solution. The functional polymer with various sulfoxide contents were synthesized and characterized by means of IR, 1H-NMR, X-ray diffraction and thermal analysis, etc. The results showed that crystallinity of the functional polymer decreased with increasing content of sulfoxide group in the polymer, and its solubility in cold water, dimethylsulfoxide, methanol, ethanol and dichloromethane was enhanced. |
