Abstract
A polymerization reactor for creating drag-reducing polymer having a reservoir and at least one heat exchanger plate in fluid communication with a coolant source, wherein each heat exchanger plate may be disposed on a lid. The heat exchanger plates are treated and/or covered to provide that the exchanger plates can be readily disengaged from the drag-reducing polymer. The polymerization reactors of the present invention permit large amounts of polymer to be formed in each reactor batch. Preferably, polymers are formed in the polymerization reactor by bulk polymerization. Methods for forming drag-reducing polymers are also disclosed.
