Abstract
The present invention discloses a continuous process for the production of anionically-polymerized organic materials having controlled architectures. The organic materials may be made from one or more temperature-sensitive anionically-polymerizable monomers. The materials are made under plug-flow and temperature-controlled conditions.
Claims24
A continuous process for making an anionically-polymerized organic material having a targeted architecture comprising
- a) introducing into a plug flow reactor having one or more temperature controlled sections a reaction mixture comprising at least one anionically-polymerizable monomer, an initiator system, and a solvent system such that the monomer concentration is 10 to 50 weight %;
- b) allowing the monomer to polymerize as the reaction mixture is laterally mixed as it travels in an essentially plug flow manner through the reactor;
- and
- c) discharging the polymerized organic material.
