A sulfur-based, chain-transfer agent providing a high degree of control for living radical polymerizations utilizing the RAFT (reversible addition-fragmentation chain-transfer polymerization) technique.
The trithiocarbonates have a structure that contains three sulfur atoms.
All three sulfur atoms can participate in bonding to the mineral surfaces. Philips
Petroleum Company did most of the development of this class of collectors. Monoalkyl
trithiocarbonate (Orfom 800 series) is used as a collector in flotation of copper and
copper–lead ores.
