Abstract
Poly(phenylene sulfide) is a polymer composed of a series of alternating aromatic rings and sulfur atoms. The conventional process for manufacturing PPS is explained. The use of catalyst, modifiers, and cleanup is described. PPS as such can be modified with nitro groups as common by a mixture of nitric acid and sulfuric acid. High thermal composites from PPS and boron nitride have been prepared by melt compounding. Mechanical, thermal, electrical, and optical properties of PPS are discussed.The isothermal crystallization behavior of PPS with different molecular weights under shear stress has been investigated. PPS are useful materials for electrical and electronic parts and appliances, and as high rigidity materials for various applications.
