“…Several expressions have been used to predict phase inversion in polymer blends. The most often used gives the composition where co-continuous phases exist by the semi-empirical expression2') ?I @22/V2@1 = 1 (4) where q and q5 are the viscosity and the composition, respectively, of each component. Using the torque ratio instead of the viscosity ratio, the phase inversion corresponds to a PEEK concentration of approximately 70%.…”

Poly(ether ether ketone) (PEEK)/polysulfone (PSF) blends were obtained by kneading and compression moulding over the whole composition range. The blends were then both quenched and slowly cooled. Both cooling procedures provided blends with two practically pure phases and good small strain properties. Ductility was worsened, as expected, in slowly cooled blends. However, in quenched blends, which provided less phase-separated fracture surfaces and no very different free volume, ductility showed unexpected good values which are tentatively attributed to common features of the chemical structure of both blend components.

“…The introduction of a variety of stiff and bulky groups such as biphenyl or naphthalene into the polymer backbone is one of the common approaches for increasing T g because it offers good advantages concerning the stability and thermal resistance of the resulting polymer . The copolymerization of PEEK was also investigated in order to improve its glass transition temperature ( T g ), and processability at high temperatures, and to obtain low‐cost materials, but the improvement of T g is not so marked for those reported PEEK copolymers.

A new monomer, 2,6-bis(4-phenoxybenzoyl)naphthalene (BPOBON), was easily synthesized via simple synthetic procedures from readily available materials. A series of novel poly(aryl ether ketone)s containing both 2,6-naphthylene moieties and amide linkages in the main chains were prepared by the Friedel-Crafts acylation solution copolycondensation of isophthaloyl chloride with a mixture of BPOBON and N,N'-bis(4-phenoxybenzoyl)-1,4-phenylenediamine (BPBPPD), over a wide range of BPOBON/BPBPPD molar ratios, in the presence of anhydrous AlCl 3 and N-methylpyrrolidone in 1,2-dichloroethane. All the polymers are semicrystalline and had remarkably increased T g s over the conventional PEEK and PEKK due to the incorporation of naphthalene and amide linkages in the main chains. The polymers with 50-70 mol % BPOBON had not only high T g s of 179-186C, but also moderate T m s of 321-328 C, which are very suitable for the melt processing. These polymers had tensile strengths of 101.5-107.1 MPa, Young's moduli of 2.13-2.39 GPa, and elongations at break of 11.8-13.7% and exhibited excellent thermal stability and good resistance to organic solvents.

“…PEEK or PEK) suffer from poor creep behavior above their relatively low glass transitions, the synthesis of semicrystalline poly(aryl ether ketone)s with increased T g is of considerable interest. In recent years, some papers were published concerning the copolymerization of PEEK in order to improve its glass transition temperature ( T g ), and processability at high temperatures, and to obtain low‐cost materials . But, the improvement of T g is not so marked for those reported PEEK copolymers.…”

Newmonomers, 4,4 0 -bis(4-phenoxybenzoyl)diphenyl (BPOBDP) and N,N 0 -bis(4-phenoxybenzoyl)24,4 0 -diaminodiphenyl ether (BPBDAE), were conveniently synthesized via simple synthetic procedures from readily available materials. Novel copolymers of poly(ether ketone diphenyl ketone ether ketone ketone) (PEKDKEKK) and poly(ether amide ether amide ether ketone ketone) (PEAEAEKK) were synthesized by electrophilic FriedelCrafts solution copolycondensation of isophthaloyl chloride (IPC) with a mixture of BPOBDP and BPBDAE, over a wide range of BPOBDP/BPBDAE molar ratios, in the presence of anhydrous AlCl 3 and N-methylpyrrolidone (NMP) in 1,2-dichloroethane (DCE). The copolymers obtained were characterized by different physicochemical techniques. The copolymers with 10-40 mol% BPBDAE are semicrystalline and had remarkably increased T g s over commercially available PEEK and PEKK due to the incorporation of amide and diphenyl linkages in the main chains. The copolymers IV and V with 30-40 mol% BPBDAE had not only high T g s of 185-188 C, but also moderate T m s of 326-330 C, having good potential for the melt processing. The copolymers IV and V had tensile strengths of 101.7-102.3 MPa, Young's moduli of 2.19-2.42 GPa, and elongations at break of 13.2-16.6% and exhibited high thermal stability and excellent resistance to organic solvents.
