聚合物加氢催化剂的研究进展

Advance in the catalytic hydrogenation of polymers

随着聚合工艺的不断进步,含有不饱和双键的聚合物高分子种类越来越丰富,对其进行加氢改性也随之愈发重要。综述了聚合物加氢催化剂的研究进展,包括齐格勒-纳塔催化剂(Z-N催化剂)、茂金属催化剂、贵金属络合物催化剂以及非均相催化剂,并总结催化剂的催化机理和影响催化剂活性的因素,对其发展方向进行展望。

With the continuous progress of polymerization process,the variety of polymer macromolecules containing unsaturated double bonds is becoming more and more abundant,and the hydrogenation modification of them is also becoming more and more important.The research progress of polymer hydrogenation catalysts,including Ziegler-Natta catalysts(Z-N catalysts),metallocene catalysts,noble metal complex cata-lysts,and non-homogeneous catalysts,is reviewed.The catalytic mechanism of the catalysts and factors affecting the catalytic activity are summarized,and the direction of their development is prospected.
