Synthesis of Acrylate and Alkyl Acrylate Monomers and Polymers of Chelators

摘要

Multifunctional chelating groups are covalently bound to acrylate or methacrylatemonomers. These monomers are polymerized. The resulting polymers are highly substituted with chelating groups and are useful for removing metals from fluids such as liquid hydrocarbons. An example of a polymer according to this invention has the following structure: (structural formula) wherein Q is a saturated or unsaturated aliphatic group having 1 to about 200 carbon atoms and is typically an unsubstituted unbranched alkylene, a substituted unbranched alkylene, a substituted branched alkylene, or an unsubstituted branched alkylene, and n is an integer having a value of at least 1.
