Investigating of polysulfide and epoxy‐polysulfide copolymer curing

Materialwissenschaft und Werkstofftechnik, 2010
AbstractPolysulfide 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, 1962
E 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 Sealants

Rubber Chemistry and Technology, 1981
Abstract Sealants based on polysulfide liquid polymers are widely used in a number of applications. These sealants are solvent and chemical resistant, having good flexibility and adherence to many substrates such as steel, aluminum, glass, concrete, wood, etc.

Modification of polysulfide sealant with polysulfide polythio‐urethane‐urea

Journal of Applied Polymer Science, 2007
AbstractWith a small amount of isocyanate‐terminated polysulfide (NCO‐PSF‐NCO) as additive, the commercial polysulfide‐based sealant had significant improvement in mechanical properties. The test results showed that 5% of NCO‐PSF‐NCO could help to rise 50% in the tensile strength and 27% in the ultimate elongation of the polysulfide sealant.

Polysulfide Complexes of Metals

1987
Publisher 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 Polymers

Rubber Chemistry and Technology, 1950
Abstract The chemistry of the condensation polymerization is reviewed briefly. The structures of the polymeric products as well as the effects of copolymerization, cross-linking, end groups, and molecular weight upon polymer properties are discussed.

Polysulfide Coordination Clusters of the Lanthanides

Angewandte Chemie International Edition, 2017
AbstractThe 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).
