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.
将具有环氧乙烷（EO）和环氧丙烷（PO）两种不同封端基团的聚亚烷基二醇用于胺化反应，以在钴基催化剂上制备聚醚胺（PEA）。虽然已知仲醇的胺化比伯醇更困难，但与EO封端的嵌段共聚物相比，PO封端的嵌段共聚物对PEA表现出显著增强的活性和对伯胺的选择性。
