AROMATIC POLYETHER |
摘要 |
<p>A tough crystallisable aromatic polyether having a Tg (annealed) of at least 160 DEG C contains within its chain the repeat units -Ph-CO-Ph- I -[Ph-SO2-Ph]n- II at a molar ratio I/II in the range 98:2 to 80:20 where Ph represents paraphenylene; the repeat units are linked through ether oxygen; and n is at least 1.1. It can be made by reacting together in suitable conditions hydroxy and halogeno aromatic compounds corresponding to units I and II and to any minor units that are to be present. The reactants can be provided at least partly by an oligomer or polymer containing an ether-linked succession of the units.</p> |
