金属有机高分子催化剂分子式：CAS号：性质：指含金属的高分子试剂和高分子催化剂，也称为金属有机高分子试剂和催化剂。根据聚合物骨架与金属的结合方式不同，可分成：(1)聚合物与金属以共价键相结合，其结构与效能类似于小分子同类试剂；(2)聚合物与金属之间以离子键结合，往往是以离子交换树脂为基体，与金属离子相结合，这种试剂如果在反应中金属离子的价态发生变化，会影响两者的结合力；(3)聚合物与金属之间的结合主要依靠配位键，这时聚合物是含有各种配位基团的高分子络合剂，与过渡金属络合后常具有催化活性；(4)聚合物与金属之间依靠物理吸附作用相结合，这种聚合物主要是一些高分子吸附树脂，其化学反应性能主要取决于所吸附的金属离子或金属有机化合物。由于这种吸附作用力比较小，影响试剂的稳定性和使用效能，使用范围受到一定限制。
