Abstract:
Polymers having amine sulfide terminal moieties are provided. The amine sulfide terminal moieties are imparted by using aminethiols 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.
