POLYMER COMPOSITION

A curable polymer composition comprising a polymerisable cyanate ester thermoset component and a polyarylsulphone thermoplast component containing ether- and/or thioether- linked repeating units (PhSO2Ph)n and (Ph)a where Ph is phenylene, a and n are independently 1 to 2 and may be on average fracti...

Beschreibung
Zusammenfassung:	A curable polymer composition comprising a polymerisable cyanate ester thermoset component and a polyarylsulphone thermoplast component containing ether- and/or thioether- linked repeating units (PhSO2Ph)n and (Ph)a where Ph is phenylene, a and n are independently 1 to 2 and may be on average fractional and the the phenylenes in (Ph)a are linked by a single chemical bond. Preferably the polyarylsulphone carries end groups providing active hydrogen and has a molecular weight over 5000. The composition may contain reinforcing fibres. In a structure made by curing such a composition the polymers components may be combined in a network in which each extends continuously or in which islands of predominantly thermoset resin are dispersed in a continuous phase of predominantly thermoplast polymer.
