| 摘 要： | 本文介绍了用反复冻结～融溶过程制备高含水聚乙烯醇弹性体的方法,并测定了该弹性体的机械、溶解和溶胀性能。结果表明,该弹性体可同时具有很高的含水率(85—90％)和较高的抗张强度(10~5—10~6Pa),且在37℃的水中有良好的稳定性能。

| Abstract: | High water content poly (vinyl alcohol) elastomers were prepared by repeated freezing-thawing process and the mechanical properties, degree of swelling and solubility of the elastomers have been studied in detail. The results show that the elastomers have both high water content (85-90%) and high tensile strength (105-106Pa) simultaneously and their properties have excellent stability when soaked in water at the temperature of 37℃. |
