Poly sulfide fillers

Carbon black filled NR vulcanisates have been studied by high-resolution solid-state 13C NMR at 75.5 MHz. It is shown that the detection of poly- and mono-sulfidic crosslinks with 13C MAS spectroscopy is also possible in the case of carbon black filled NR vulcanisates. Quantitative results suggest that the addition of carbon black leads to a decrease in crosslink density with increasing filler content [55]. 

MAJOR APPLICATIONS Poly(p-phenylene sulfide) (PPS) is mainly used in the reinforced form with glass fiber or mineral fillers as a high-performance thermoplastic. It is used for electrical and electronic parts (e.g., plugs and multipoint connectors, bobbins, relays, switches, encapsulation of electronic component, etc.), automobile parts (air intake systems, pumps, valves, gaskets, components for exhaust gas recirculation systems, etc.), and as components for mechanical and precision engineering. Nonfiller PPS is used for fiber, film, sheet, nonwoven fabric, etc.

FTIR spectroscopy has been applied in the study of polymer blends including Neoprene rubber, chlorosulfonated PE, nitrile rubber, polyvinyl chloride (PVC) containing carbon black and other fillers [86], Nylon 6 inorganic [87], polyhydroxyether sulfone/poly(N-vinyl pyrrolidone) [88], graphite-based low-density polyethylene [89], caprolactone/Nafion blends [90], polybutylene terephthalate/polyamide [91], polyphenylene sulfide/acrylonitrile - butadiene - styrene [92], PMMA/polypyrrol [93], and lower or high performance liquid chromatography (LDPE/HDPE) [94]. 

Typical blend polymers for PBI include poly (aryl ether ketone) (PARK), pofyetherimide (PEI), poly (aryl ether sulfone), poly (phenylene sulfide), and mixtures thereof. Different types of PAEK resins (Fig. 7.5) include PEK, PEEK, PEKEKK, PEKK, PEEKK, etc., several of which have melting points over 300°C. PAEK resins with relatively low Tg values can be further improved by the addition of reinforcement fillers, such as fiberglass, carbon fibers, and ceramic or mineral fillers. Such additions, however, can...
