polysulfide

We became the only producer of polysulfide chemicals in the world.

The trisulfide ion, S is part of the polysulfide series.

Chemical burns from calcium polysulfide were responsible for most of the severe cases.

Here, another electron reacts with sulfur to form S, sodium polysulfide.

The active ingredient is probably a calcium polysulfide, not CaS.

Another way to make it is with polysulfide dissolved in hexamethylphosphoramide where it gives a blue colour.

Except for polysulfide toners, sepia toning is done in three stages.

Disulfide and (polysulfide) bonds are the crosslinking groups that result from the vulcanization of rubber.

The polysulfide anions adopt zig-zag chains of sulfur atoms.

"Thiokol" polymers arise when sodium polysulfide is treated with an alkyl dihalide.

"The intent is to have no paths at all" through the polysulfide adhesive, said Mr. Winterhalter.

High-performance caulks containing polysulfide, polyurethane, ethylene copolymer and other compounds compete well.

In the course of an experiment involving ethylene dichloride and sodium polysulfide, they created a gum whose outstanding characteristic was a terrible odor.

Triphenylphosphine abstracts sulfur from polysulfide compounds, episulfides, and elemental sulfur.

However, the production of polysulfide ions from S and S is thermodynamically favourable:

In commerce, the term "polysulfide" usually refers to a class of polymers with alternating chains of several sulfur atoms and hydrocarbons.

Concentrated polysulfide solutions and solid polysulfides explode on contact with 30% hydrogen peroxide and possibly other strong oxidizing agents.

It claims to use Kodak BrownToner, a polysulfide film treatment, on every reel of silver-halide microfilm that they produce.

In solutions, sodium tetrasulfide exists in equilibrium with other polysulfide ions, such that additional sulfur converts the dianion to still longer chains.

An environmentally benign garlic-derived polysulfide product is approved for use in the European Union (under Annex 1 of 91/414) and the UK as a nematicide.

Attempting to make a polysulfane by acidifying an alkali metal polysulfide salt (e.g. sodium disulfide) simply produces hydrogen sulfide, HS, and sulfur.

Offering stiff competition to silicone caulk in recent years are polysulfide, polyurethane, acrylic, siliconized and other caulks - all of which are high performance and long lasting.

Liver of Sulfur is a poorly defined mixture of potassium sulfide, potassium polysulfide, potassium thiosulfate, and probably potassium bisulfide.
