Cyclic oligo(arylene ether)s, processes for their preparation and their use |
| abstract |
The invention relates to a process for the manufacture of a cyclic oligo(arylene ether) which can be a cyclic oligo(dichloromethylene arylene ether) or a cyclic oligo(arylene ether ketone); the process comprises the step of causing an aromatic compound to react with a hexachloroxylene compound in a pseudo-high dilution environment. The invention relates also to new cyclic oligo(arylene ether)s and their use for the manufacture of acyclic poly(arylene ether)s, such as PEKK, by ring-opening polymerization. |
