Abstract

The issue of the use of mixtures of organochlorine products from epichlorohydrin production wastes to yield the commercially valuable sulphur-containing polymers, thiokols, is considered. It has been demonstrated that carrying out the reactions of mixtures of organochlorine compounds of various composition with sodium polysulphide in non-aqueous media (methanol) allows one to obtain powdered solid polymers, namely, polyorgano polysulphides, with 66-90 % yield and with high content of sulphur, up to 82 %. The analysis of possible ways of formation of polymers is performed; their physicochemical and structural properties are studied; suggestions are given concerning the ways of putting to work.
