摘要

The present chapter discusses the pilot plant scale synthesis of ceramic precursor polymeric materials, Polydimethylsilane (PDMS) and Polycarbosilane (PCS), as well as organic polymers, Polyetheretherketone (PEEK), and Polyurethane (PU) for the development of production technologies of strategic structural materials such as SiC and other modular capacities in several Defence applications. A detailed description of PEEK by reacting 4,4′-difluorobenzophenone, hydroquinone, K2CO3, and using diphenylsulphone (DPS) as a solvent is provided. Similarly, the reaction process is illustrated for PU by the Prepolymer route. Several key characterisations of PCS, PDMS, PEEK, and PU are also described.
