Polyfether ketone

Scheme 6.7 Synthesis of polyfether ketone ketone) via aromatic electrophilic substitution catalyzed by AICI3.

Kricheldorf et al. used trimethylsilylated phenols to react with activated difluoro monomers, such as DFBP, in the presence of catalytical amounts of CsF to prepare polyfether ketone)s.80,81 The polymers were prepared in the melt without solvent and can be directly processed. 

Atsushi Morikawa studied organic materials science at the Tokyo Institute of Technology. In 1992 he obtained his doctor s degree on siloxane dendrimers and polyimide-silica hybrid materials by sol-gel method. After a two-year spell as a research engineer at Asahi Chemical Company, he transferred to the Faculty of Engineering at Ibaraki University to continue his research on polyfether ketone) dendrimers and polyimides.

The curves in the lower right of Fig. 3.98 illustrate a point-by-point determination of not only the crystallinity, but also the nature of the crystallization as a function of time. The example polymer is apoly(oxy-1,4-phenylene-oxy-l, 4-phenylene caibonyl-1,4-phenylene) or simply polyfether ether ketone), PEEK. After the given time at the...

Firebrake ZB 415 with Dechlorane Plus gives flame-retardant properties superior to those of antimony oxide alone. Grade ZB 500 makes it possible to suppress fumes from fluoropolymers, and gives good flame-retardant properties to poly(ether ketone)s and polyfether sulphone)s. Other key applications are talc-reinforced PP replacing PVC. ABS, and PA 66 in electrical/electronic applications, and EVC cable compounds.
