ABSTRACT:
Polymers having amine sulfide terminal moieties are provided. The amine sulfide terminal moieties are imparted by using amine-thiols as chain transfer agents in aqueous addition polymerizations.
The polymers are useful as mineral dispersants, as water-treatment additives for boiler waters, cooling towers, reverse osmosis applications, sugar refining, paper production, geothermal processes and oil wells, and as detergent additives acting as builders, anti-filming agents, dispersants, sequestering agents and encrustation inhibitors.
