Investigating of polysulfide and epoxy‐polysulfide copolymer curing
Materialwissenschaft und Werkstofftechnik, 2010AbstractPolysulfide can be cured in various methods. In this work, the effect of various oxidative curing agents (manganese dioxide and para quinonedioxime) in presence of curing accelerator (Diphenylguanidine) on mechanical‐dynamical properties and cure time of polysulfide resin (G4) was investigated.

The transulfuration of sulfinates by polysulfides
Experientia, 1962E stato dimostrato che la transulfurazione che consegue alla incubazione dei solfinati con zolfo ed un composto tiolico e dovuta in parte alla produzione di un polisolfuro organico, formato dal tiolo e zolfo, ed in parte al polisolfuro inorganico, formato dalla decomposizione di quello organico. L'entita della transulfurazione prodotta direttamente dal

Polysulfide Complexes of Metals
1987Publisher Summary Sulfide minerals were formed mostly hydrothermally from postmagnetic fluids; it appears remarkable that the formation of many ore deposits cannot be conclusively explained because of the very low solubility of the corresponding sulfide.

Polysulfide Coordination Clusters of the Lanthanides
Angewandte Chemie International Edition, 2017AbstractThe reaction of [(DippForm)2Ln(thf)2] with an excess of elemental sulfur in toluene resulted in the formation of the trinuclear polysulfide coordination clusters [(DippForm)3Ln3S12] (Ln=Sm, Yb; DippForm=N,N′‐bis(2,6‐diisopropylphenyl)formamidinate).

Disulfides and polysulfides have the structure R1SSnR2, in which chains of sulfur atoms are terminated by two groups that may be the same, different, or connected in a ring. Chapter 7 considers only substances where the S-R bond involves a carbon linkage; a review is available of structures such as ROSnOR and R2NSnNR2) Disulfides (n = 1) and their ...
