POLYMERIZATION PROCESS WITH CATALYST REACTIVATION |
摘要 |
<p>Polymerization processes of the present invention comprise low catalyst concentration. Embodiments include a polymerization process comprising polymerizing free radically (co)polymerizable monomers in a polymerization medium comprising one or more radically (co)polymerizable monomers, a transition metal catalyst complex capable of participating in a one electron redox reaction with an ATRP initiator; a free radical initiator; and an ATRP initiator; (wherein the concentration of transition metal catalyst complex in the polymerization medium is less than 100 ppm). Further embodiments include a polymerization process, comprising polymerizing one or more radically (co)polymerizable monomers in the presence of at least one transition metal catalyst complex; an ATRP initiator; and a reducing agent; wherein the transition metal catalyst complex is present at less than 10−3 mole compared to the moles of radically transferable atoms or groups present on the ATRP initiator.</p> |
