PPE in Thermoset Resins

PPE has been used in thermosets. In particular, PPE is used in the resin formulations to make GETEK copper-clad laminates for high-end, high-performance printed wiring boards. GETEK laminates were developed by GE Electromaterials. Epoxy-PPE based laminates were commercialized in 1991 [28]. In 2002, PPE-cyanate ester based laminates were 

In thermosets prepared via free-radical polymerization, the terminal OH end group of PPE needs to be capped because the aromatic hydroxyl will act to quench free radicals and inhibit the polymerization [30, 31]. Capping the OH with a reactive group facilitates incorporating the PPE into the thermoset matrix [32]. 

In 2003, GE Advanced Materials introduced Noryl ETX resins, which are designed to enhance the performance of thermoset resins. 

The successful use of engineering thermoplastics for end-use applications is dependent on important criteria such as 

Selection of the proper resin grade that will give the desired performance
