WebNov 1, 1977 · Polyetherketone (PEK) is a semi-crystalline polyether that was first developed by K. Dahl of Raychem in the 1970s for captive use. The Friedel-Crafts process required strong solvents or an excess of aluminum chloride to keep the polymer in solution. PEK has a T m of 364°C and a T g of 166°C. Polyether ether ketone (PEEK) is a colourless organic thermoplastic polymer in the polyaryletherketone (PAEK) family, used in engineering applications. The polymer was first developed in November 1978, later being introduced to the market by Victrex PLC, then Imperial Chemical Industries (ICI) in the early 1980s.
