The effective application of the complex of copper - polyamide amine (Cu (II)-PAMAM) as a catalyst.

Advantages of Cu(II)-PAMAM complexes as catalyst in aqueous medium in the DMP polymerization: (1) can be carried out under relatively mild conditions; (2) good coupling selectivity of C-O/C-C , high yield rate of polymer polyphenylene ether (PPO),minimal byproduct DPQ; (3)compared with traditional Cu (II)-EDTA complex catalyst, the catalytic activity of Cu (II)-PAMAM complex is greatly improved.
