The synthesis routes and the properties of PENs are reviewed in this chapter. Monomers for PEN are summarized. PENs have been prepared according to a nucleophilic route and an electrophilic route. PEKs that are subsequently end capped with nitrile functions have been prepared by Friedel-Crafts polymerization. A general method to prepare cyclic oligomers has been described. The cyano group, because of its polarity, imparts good adhesion properties to glass fibers.Thermoplastic resinous compositions that contain PEN have found wide uses because of their excellent thermal resistance and mechanical strength. Fields of application like aerospace, electrical coatings, and in automotive components are described. This chapter also discusses nanocomposites, films, and hollow glass microspheres.
