Notes:
The hydrolysis of (SN)x, in air at room temperature and 90% relative humidity has been studied using the attenuated total reflectance (ATR) method. Decomposition gave rise to strong bands at 3210 and 3150 cm-1 [v3 and v1 (NH+4)], 1420 cm-1 (vb NH+4), 1220 cm-1 (S=O), 1089 and 610 cm-1 [v1 and v3 (SO2-4)]. For the first 3 days, the decay of the 808 and 690 cm-1 bands of (SN)x was first order, with a half life of about 30 h. The spectroscopic data were consistent with the rapid formation of —SO2—NH2 and =S=NH chain end groups with subsequent relatively slow hydrolysis to (NH4)2SO4, sulfur, and fresh hydrolysable chain ends.
