ABSTRACT:
Polymerization process providing for the transferring of heat from fluid reaction mixtures containing a polymerizable monomer and an active polymerization catalyst by preparing a prepolymerization mixture and then cooling the prepolymerization mixture using a planar spiral heat exchanger before further processing of the prepolymerization mixture or the polymer product contained therein. An apparatus for conducting polymerization reactions wherein fluid mixtures having a polymerizable monomer and an active polymerization catalyst are cooled without clogging comprising a spiral heat exchanger.
