Abstract

PURPOSE: To synthesize simply and at low cost a polyalkylene sulfide in a one-stage process, by reacting an aq. soln. of an alkali metal sulfide with an alkylene halide by using a phase transfer catalyst.
CONSTITUTION: An aq. soln. of an alkali metal sulfide (e.g. sodium sulfide or potassium sulfide) is reacted with an alkylene halide having the formula X-R'-Y (wherein R' is 1W20C bivalent alkylene group, X, Y are halogen) (e.g. dichloromethane or bromochloromethane) by using a phase transfer catalyst (e.g. trioctylmethylammonium chloride) to produce a polysulfide having a repeating unit of the formula -(R-S)-(wherein R is a bivalent org. group) (e.g. polymethylene sulfide). The inexpensive alkali metal sulfides can be used. The polyalkylene sulfide can be produced even if a large amount of water is present. When the process is directed to produce polymethylene sulfide, the polymer can be obtd. in a one-stage process without isolating the intermediate, a cyclic oligomer.
