Polysulfides are a class of chemical compounds containing chains of sulfur atoms. There are two main classes of polysulfides: anions and organic polysulfides. Anions have the general formula S 2−

Aliphatic polysulfides, also known as thiokols or poly(alkylene sulfide)s, are another Cure to high molecular weight elastomers can be achieved by oxidizing the and solvents including aliphatic and aromatic hydrocarbons, ethers, ketones,
29 Mar 2016 This was related to the ester group of the substrates, which is .. This irregularity in the polymers' structure also affects thermal properties. . Table 2. Melting Points of Different All-Aliphatic Linear Polyesters of the PE-X.Y and PE-X Typea .. polyterephthalates, and polysulfides), estimating the minimum for
Organosulfur compounds are organic compounds that contain sulfur. They are often associated The bond dissociation energies for dimethyl sulfide and dimethyl ether are Aliphatic thiols form monolayers on gold, which are topical in nanotechnology. Thioamides, with the formula R1C(=S)N(R2)R3 are more common.
Polysulfide resin . is expressed by the formula shown below; the active hydrogen in primary amine reacts with an glycidyl-ether type resins easily cure at room temperature, but Resins that have been cured using aliphatic amines are strong, and are Table 1. Properties and performance of amine based curing agents.
