摘要 |
A water soluble polyvinyl alcohol copolymer having a diad syndiotacticity of greater than about 60% and less than about 70%. In some embodiments, the water soluble polyvinyl alcohol copolymer is soluble in water at a concentration of at least 1 wt % at a temperature of less than 100° C. In other embodiments, the composition is soluble in water at a concentration of at least 5 wt % at a temperature in the range from about 90° C. to less than 100° C. The high solubility of the high syndiotactic poly vinyl alcohols disclosed herein may provide various advantages as described herein, including ease of processing and decreased use of harmful solvents. |
