POLYMERIC MATERIALS

Polyaryletherketones are produced which are end-capped with a phenylethynyl-containing moiety. The end-capped material, having a relatively low molecular weight, may be subjected to a thermal cycle to produce a higher molecular weight material having excellent mechanical properties, a relatively hig...

Zusammenfassung:	Polyaryletherketones are produced which are end-capped with a phenylethynyl-containing moiety. The end-capped material, having a relatively low molecular weight, may be subjected to a thermal cycle to produce a higher molecular weight material having excellent mechanical properties, a relatively high level of crystallinity and acceptable Tm and Tg
