摘要 |
The present invention provides a method of preparing an amine-functionalised (e.g. amine-terminated) polyaryletherketone polymer, or imide- or sulphone-copoiymer thereof and amine-protected analogues thereof, said method comprising the step of polymerising a monomer system in a reaction medium comprising a capping agent comprising -NR2, -NRH or a protected amine group. |
