Preface xxiii

liquid crystal polyesters, poly(butylene terephthalate), polyamides, and
PTFE. Work on these blends is amply referenced in the chapter, which
points out that “of the various reported blends of PPS with other polymers,
only blends of PPS with ethylene-copolymer impact modifiers, polyamides,
and PTFE are beginning to show wide utility in applications for reinforced
plastics.”
Reinforced PPS-specific design considerations, and injection-molding
and compression-molding parameters are described in this chapter. Woven-
fabric-reinforced thermoplastic PPS compounds are thermoformed, fila-
ment wound, and pultruded; and new blow molding reinforced PPS
compounds are being developed by Chevron Phillips Chemical according
to the authors. Reference 135 (published in 2002) in the chapter cites
blow-moldable PPS for large automotive ducting. The chapter describes
machining and assembly methods for reinforced PPS compounds.
