20090156771 | Amine-Containing Compounds for Enhancing the Activity of ATRP Catalysts and Removal of the Terminal Halogen Groups from the ATRP Polymer Products - Disclosed are new, highly active and versatile atom transfer radical polymerization (ATRP) catalysts. These catalysts catalyze ATRP for acrylates, methacrylates, and styrenes at surprisingly low concentrations. These catalysts mediated ATRP at a catalyst/initiator molar ratio at 0.005 and produced polymers with well-controlled molecular weights and low polydispersities. ATRP occurred even at a catalyst/initiator molar ratio as low as 0.001 with metal concentration in the produced polymers as low as 6-8 ppm. Amine-containing compounds, such as triethylamine, can significantly increase the catalyst activity of theses catalysts. The amine compounds can also used to the terminal halogen groups such as Br and Cl in the polymers prepared by ATRP. | 06-18-2009 |
