ABSTRACT:
An annular reactor for polymerizing and copolymerizing vinyl esters characterized by the fact that the height to width ratio is greater than 1 and preferably greater than 5, that there is a circulating pump in the lower leg of the reactor and that the pump delivery volume of the reactor is between 5 and 30 percent of the reactor total volume, and preferably about 15 percent of the reactor total volume. Methods of polymerizing and copolymerizing vinyl monomers in such a reactor are also disclosed.
