Abstract: A series of poly(aryl ether ketone)s containing meta-phenyl links are synthesized,DSC and wide-angle X-ray scattering,etc.are used to study the general properties of the polymers.With the increasing of meta linkage monomer percentage,the melting temperature decreases sharply at first,then rises steadily,the glass transition point keeps a stable value,and crystallinity and crystallizing rate are reduced.Apart of amorphous film of the polymer is annealed at different temperatures.DSCscan shows that besides Tm,a new melting peak( T'm)at low temperature appears.And with heat treating temperature rising,T'm shifts to high temperature, and Tm keeps a stable value.

Key words: Poly(aryl ether ketone)s, meta-Phenyl links, Melting temperature, Crystallinity
