Sv. Amosova et al., POTASSIUM N-(VINYLOXYETHYL)DITHIOCARBAMATE AS AN EFFICIENT AGENT FOR REMOVING METAL-CONTAINING CATALYSTS FROM POLYMERS, Russian journal of applied chemistry, 67(5), 1994, pp. 745-747
A highly efficient method is suggested for removing residual catalysts
of cationic polymerization (FeCl3, AlCl3, TiCl4, and SnCl4) from solu
ble and swelling polymers, by means of potassium N-(vinyloxyethyl)dith
tiocarbamate solutions in. DMSO, DMF, benzene, toluene, or water.
