Abstract
In a reactor for continuous polymerization in which an olefinic monomer is polymerized by contacting the olefinic monomer under suitable reaction conditions with an initiator, the formation of residue in the reactor is reduced by introducing the olefinic monomer and initiator into opposite sides of a turbulent zone produced by an agitator in the reactor. This improves mixing of the olefinic monomer and the initiator and prevents the initiator from contacting high concentrations of the olefinic monomer which results in reduced residue formation in the reactor.
