http://ijamtes.org/gallery/239-dec.pdf A variety of thiokols are recognized. Typically they are prepared by the combination of 2-chloroethanol, formaldehyde, and sodium polysulfide (Na2Sx). The chloroethanol is produced in situ from ethylene oxide and hydrogen chloride. The rank x of the polysulfide is an important variable. Crosslinking agents are used, such as 1,2,3-trichloropropane. An idealized polymer is represented by this formula HS(CH2CH2OCH2OCH2CH2SS)nCH2CH2OCH2OCH2CH2SH. Thiol-…
