Polyether ether ketone (PEEK) is a colourless organic thermoplastic polymer in the polyaryletherketone (PAEK) family, used in engineering applications. It was invented in November 1978 [2] and brought to market in the early 1980s by part of Imperial Chemical Industries (ICI), the PEEK division was acquired through a management buyout, giving rise to Victrex PLC.
Polyetherketones (PEK for short) are polymers whose molecular backbone contain alternating ketone (R-CO-R) and Ether (R-O-R) functionalities. The most common are Polyaryletherketones (PAEK), in which there is an aryl group linked in the (1–4)-position between each of the functional groups.

It also affects its heat resistance and processing temperature. The higher the ratio of ketones the more rigid the polymer chain, which results in a higher glass transition temperature and melting point. The processing temperatures can range from 350 to 430 °C. [1] [3] [4] Plastics that fall within this family include: [3] PEK; PEEK; PEKK; PEEKK

The introduction paragraph says: Polyether ether ketone (PEEK) is a colourless organic thermoplastic polymer in the polyaryletherketone (PAEK) family, used in engineering applications. This aryl in polyaryletherketone mustn't be confused with acryl. Steue 21:15, 24 January 2021 (UTC)
The instrument uses special molded rings of polyether ether ketone (PEEK). [ 4 ] By May 2017, some of the first scientific analyses reported that JADE observed plasma coming up from the upper atmosphere of Jupiter into the magnetosphere. [ 5 ]
[2] In manufacturing processes by polycondensation a high purity of the starting materials is important. In addition, the stereochemistry plays a role in achieving the desired properties in general. The development of new high-performance plastics is therefore closely linked to the development and economic production of the constituent monomers ...
