Apparatus and methods for controlled radical polymerization

摘要

A method of conducting controlled radical polymerization, including: (a) providing a mixture of at least one monomer; at least one monomer solvent; at least one compound metal coordinating capable; and at least one initiator; (b) directing the mixture at a rate over a solid catalyst surface contained in an external chamber to the vessel, the catalyst including a metal or metal compound capable of at least two oxidation states; (c) monitoring the reaction vessel temperature; (d) adjusting the flow rate when the temperature is outside a selected temperature range; and (e) allowing the polymerization to proceed to desired conversion level.

1. A method of conducting controlled radical polymerization, comprising:
(a) Charging a vessel with a mixture of:
At least one monomer;At least one solvent for said monomer;At least one compound capable of coordinating with a metal; andAt least one initiator; (b) Directing said mixture at a flow rate over a solid catalyst surface contained in a catalyst chamber external to the vessel, said catalyst surface comprising a metal or metal compound capable of at least two oxidation states; (c) Monitoring the temperature of said vessel within a selected temperature range; (d) Adjusting said flow rate when the temperature is outside said selected temperature range; and (e) Allowing said polymerization to proceed until a desired conversion level is reached.
