    • Provided are methods for surface-modifying a rubber vulcanizate or a thermoplastic elastomer, which can cost-effectively provide a variety of functions, e.g. sliding properties or liquid leakage resistance. Included is a method for surface-modifying a rubber vulcanizate or a thermoplastic elastomer as a modification target, the method including: step 1 of forming polymerization initiation points A on a surface of the modification target; step 2 of radically polymerizing a non-functional monomer starting from the points A to grow non-functional polymer chains; and step 3 of forming polymerization initiation points B on a surface of the non-functional polymer chains, radically polymerizing a polymerizable silane compound starting from the points B, and further reacting a perfluoroether group-containing silane compound to grow functional polymer chains, or step 3′ of adding a silane compound to a surface of the non-functional polymer chains and further reacting a perfluoroether group-containing silane compound to grow functional polymer chains.
    • 提供了用于表面改性橡胶硫化橡胶或热塑性弹性体的方法,其可以成本有效地提供各种功能,例如, 滑动性能或耐漏液性。 包括用于表面改性橡胶硫化橡胶或热塑性弹性体作为改性靶的方法,该方法包括:在改性靶表面上形成聚合起始点A的步骤1; 步骤2从点A开始自由基聚合非官能单体以生长非功能性聚合物链; 以及在非功能性聚合物链的表面上形成聚合引发点B的步骤3,从点B开始自由基聚合可聚合硅烷化合物,并使含全氟醚基的硅烷化合物进一步使功能性聚合物链生长,或步骤 3',在非功能性聚合物链的表面添加硅烷化合物,进一步使含全氟醚基的硅烷化合物与生成功能性聚合物链反应。
