Polyalkylene glycols with two different end-capping groups of ethylene oxide (EO) and propylene oxide (PO) were used for amination to produce polyetheramine (PEA) on cobalt-based catalysts. Although it is known that the amination of secondary alcohol is more difficult than that of primary alcohol, PO end-capped block copolymers showed remarkably enhanced activity toward PEA and selectivity toward the primary amine compared to EO end-capped block copolymers.

环氧丙烷封端对聚亚烷基二醇胺化的影响
具有两个不同的环氧乙烷（EO）和环氧丙烷（PO）的封端基团的聚亚烷基二醇用于胺化，以在钴基催化剂上生产聚醚胺（PEA）。尽管已知仲醇的胺化比伯醇的胺化更困难，但是与EO端基封端的共聚物相比，PO端基封端的共聚物对PEA的活性和对伯胺的选择性显着提高。
