A new monomer, 1,4‐bis(4‐phenoxybenzoyl)naphthalene (BPOBN), was conveniently synthesized via a simple synthetic procedure from readily available materials. A series of novel copolymers of poly(ether ketone ether ketone ketone) and poly(ether ketone ketone ether ketone ketone) containing 1,4‐naphthylene moieties were prepared by the Friedel‐Crafts ...

Thermal stability of a novel poly(ether ether Ketone Ketone) (PK99)
Polymer Engineering & Science, 1996AbstractThe degradation of PK99 was studied by heating the polymer in both isothermal and dynamic conditions under nitrogen flow and in a static air atmosphere. In both environments this polymer's thermal stability exceeded that of PEEK. The dynamic experiments showed that in both nitrogen and air atmospheres the polymer degraded in two stages with ...

A rare case of ternary polymer miscibility has been demonstrated in the mixture (in the glassy amorphous domains) comprising three polymers: polyetherimide (PEI), a new semicrystalline meta-linked poly(ether diphenyl ether ketone) (PFDEKm). and semicrystalline poly(ether ether ketone) (PEEK).

Thermal properties of melt‐blended poly(ether ether ketone) and poly(ether imide)
Journal of Applied Polymer Science, 1999The thermal properties of blends of poly(ether ether ketone) (PEEK) and poly(ether imide) (PEI) prepared by screw extrusion were investigated by differential scanning calorimetry. From the thermal analysis of amorphous PEEK–PEI blends which were obtained by quenching in liquid nitrogen, a single glass transition temperature (Tg) and negative excess ...
