Thermal and photodegradation of polysulfide pre-polymers: products and pathways

The synthesis of polymeric sulfides by reaction of dihaloalkanes with sodium sulfide

“…They possess excellent thermal stability, weatherability, solvent resistance and oil resistance (2)(3)(4) and hence are widely used in coatings, adhesives, sealants, insulators and other applications (5)(6)(7)(8). Also, poly(alkylene sulfide)s find application in vulcanizing rubbers (9).…”

Effect of Additives on Weathering

“…Figure 15.38 shows that the rate of carbonyl formation decreases when crosslinking of polysulfide rubber increases. 204 Opposite is the case of alkyd paints when formation of aluminum ligands was used as additional crosslinking. Figure 15.39 shows that with exposure to UV progressing more crosslinks were formed in the paint.…”

Synthesis and characterization of poly(p-xylylene tetrasulfide) via interfacial polycondensation in the presence of phase transfer catalysts

“…Polysulfide polymers exhibit excellent resistance to a wide range of chemicals and have excellent physical and chemical properties [1][2]. This class of materials shows great resistance against gases, organic solvents, and ozone effects [3][4][5].…”
