<p>A polymer composition containing a polyaryletherketone and a polysulphone, where the polysulphone contains the repeating units -Ph-SO2-Ph-Ph-SO2-Ph- and -Ar- linked through ether linkages. The polysulphone contains 50 to 70% molar of the units -Ar-, and Ar may contain more than one aromatic group linked by aliphatic hydrocarbon groups, or by -SO-, -SO2- or -CO-. A composition containing a high proportion of the polyaryletherketone shows a reduced shrinkage compared to the polyaryletherketone alone. A composition containing a high proportion of the polysulphone has improved solvent resistance and stress crack resistance compared to the polysulphone alone. The composition can be used for the production of film or fibre or for wire coating or may include other additives such as fillers or fibrous reinforcing agents, eg glass or carbon fibre.</p> |
