Polyaryletherketone

For reasons that are not fiiUy understood, PPSF exhibits generally improved compatibiUty characteristics over either PSF or PES in a number of systems. An example of this is blends of PPSF with polyaryletherketones (39,40). These blends form extremely finely dispersed systems with synergistic strength, impact, and environmental stress cracking resistance properties. Blends of PPSF with either PSF or PES are synergistic in the sense that they exhibit the super-toughness characteristic of PPSF at PSF or PES contents of up to 35 wt % (33,34). The miscibility of PPSF with a special class of polyimides has been discovered and documented (41). The miscibility profile of PPSF with high temperature (T > 230° C) polysulfones has been reported (42). 

Resins for advanced composites can be classified according to their chemistry typical resins are polyaryletherketones, polysulfides, polysulfones, and a very broad class of polyimides containing one or more additional functional groups (Table 2) (see also Engineering plastics). 

On the other side of costs, the higher priced plastics continue to be marketable since they mee t required performances for certain products. As an example polyaryletherketone...

Polyaryletherketone, [-( )-C0-( )-0-( )-0], was commercialized in 1980 as Victrex . It is a tough, resin with T = 143°C and T = 334°C. Blends of PEEK with PPS show synergistic effects toward tensile and flexural strength, as well as the impact resistance.
