Polyketones PAEK

Polyketones (or chemically accurate polyaryl-etherketones (PAEK)) are a family of semicrystalline thermoplastics with high temperature stability and high mechanical strength. Some of the commercial plastics that fall within this family include those listed with their structures in Table 10.1. 

The industry classifies some of their products as polyaryletherketones (PAEK) even though PAEK also descrihes the other polyketone resins. These chemical structures of these resins differ slightly from the other polyketone resins described in this chapter those structures are generally not disclosed. 

The most common of the polyketones are PEK, PEEK, and PAEK. All are available as thermoplastic molding compounds. PAEK is available as a compression molding compound from Amoco (Kadel). PEEK is available as a compression molding, extrusion and injection molding compound from Victrex, Compound Technologies, DSM Engineering, LNP and RTP. PEK is available as an injection molding compound from RTP. 

There are also polyketone copolymers in which the structure cannot be represented by a single repeating unit. (In the field of PAEK,...
