In the simplest case, reservoirs I and II are initially filled with monomers \\(\\ce{A}\\) and \\(\\ce{B}\\), respectively. During polymerization the contents of reservoir I are continuously pumped into the reactor and the contents of reservoir II are continuously pumped into reservoir I at definite rates."},"links":[{"term":"Semi-continuous emulsion copolymerization","url":"https:\/\/goldbook.iupac.org\/\/terms\/view\/14340"}],"sources":["PAC, 2011, 83, 2229.
