FIELD: chemistry. ^ SUBSTANCE: method involves reaction of phosphorus pentasulphide with a diol or polyol and a monobasic alcohol in molar ratio (r) of the monobasic alcohol to the diol or polyol equal to or less than 4, according to the scheme: (2n+4)ROH+(n)HO-(R')-OH+(n+1)P2S5, where the number of moles of the monobasic alcohol is equal to 2n+4, the number of moles of the diol or polyol is equal to n, the number of moles of phosphorus pentasulphide is equal to n+1, the number of repeating units is equal to n, and r is the molar ratio (2n+4)/n, to obtain dithiophosphoric acid derivatives which are oxidised to obtain polymeric dithiophosphate. ^ EFFECT: improved method of producing polymeric dithiophosphate. ^ 16 cl, 15 ex, 29 tbl |
