摘要:
The present disclosure provides a process for producing a polymer, said process comprising polymerising a monomer system comprising a compound of formula: Ar- O-Ar-C(=O)-X-C(=O)-Ar-O-Ar in a reaction medium comprising a Lewis acid where: X is an aliphatic moiety and Ar is an aromatic moiety.
摘要:
The present invention provides a method of preparing a polyaryletherketone copolymer (e.g. a random or block copolymer), said method comprising: polymerising (i) a monomer system suitable for forming aryletherketone units and (ii) a comonomer in a reaction medium comprising: (a) a Lewis acid and (b) a controlling agent comprising an aromatic carboxylic acid, an aromatic sulphonic acid, or a derivative thereof; and polymers produced therefrom.
摘要:
The present invention provides a method of preparing an amine-functionalized (e.g. amine-terminated) polyaryletherketone polymer, or imide- or sulphone-copolymer thereof and amine-protected analogues thereof, said method comprising the step of polymerizing a monomer system in a reaction medium comprising a capping agent comprising —NR2, —NRH or a protected amine group.
