WEBPolyphenylene is a versatile class of polymers that boasts high thermal stability, excellent chemical resistance, and significant electrochemical properties. Derived from phenylene units, this unique material has been integral in a variety of high-performance applications.
Polyphenylene sulfide - Wikipedia
WEBPolyphenylene sulfide (PPS) is an organic polymer consisting of aromatic rings linked by sulfides. Synthetic fiber and textiles derived from this polymer resist chemical and thermal attack. PPS is used in filter fabric for coal boilers , papermaking felts , electrical insulation , film capacitors , specialty membranes , gaskets , and packings .
Poly(p-phenylene) - Wikipedia
WEBPoly (p-phenylene) ( PPP) is made of repeating p - phenylene units, which act as the precursor to a conducting polymer of the rigid-rod polymer family. The synthesis of PPP has proven challenging, but has been accomplished through excess polycondensation with the Suzuki coupling method. [1] [2]
