  • Publication number: 20220002250
    Abstract: Disclosed are chelating co-polymer compositions that are soluble in aqueous media and chelate essential metals, methods of preparation and uses thereof. The chelating compositions are comprised of two or more different monomers, at least one of which possesses metal binding or metal chelating activity. The chelating compositions are synthesized by reversible addition-fragmentation transfer (RAFT) polymerization with the aid of a suitable RAFT-mediating agent. Also described are chelating compositions that comprise hydroxypyridinone chelating groups. The ability of the chelating compositions to bind metals affects the activity of a living cells and organisms, which require the metals for cellular functions.

  • Patent number: 9309357
    Abstract: A new synthetic method of forming free radical polymerizable end terminal functionalized poloxamers and poloxamines in commercial scale batches which uses a binary system of inhibitors to eliminate the formation of high molecular weight impurities. It has also been surprisingly discovered that the inorganic impurities formed during the commercial scale synthetic process are removed by the use of resin materials.
