Liquid phase process for the polymerization of unsaturated monomers
Abstract
Abstract IN A PROCESS FOR POLYMERIZNG A MONOMER OR MONOMERS SELECTED FROM AN OLEFIN AND A VINYL MONOMER IN THE PRESENCE OF AN AQUEOUS ORGANIC MEDIUM, ADHERENCE OF THE RESULTING POLYMER TO THE INSIDE WALLS OF THE POLYMERIZATION REACTOR IS PREVENTED BY HAVING A PARTICULAR MEDIUM COMPOSITION FLOW DOWN IN SUCH A MANNER THAT SAID COMPOSITION COVERS SAID INSIDE WALLS. SAID COMPOSITION COMPRISES A SMALL AMOUNT OF A MONOMER OR MONOMERS AND A MIXTURE CONSISTING OF SUBSTANTIALLY THE SAME COMPONENTS AS SAID AQUEOUS ORGANIC MEDIUM. SAID COMPOSITION MAY TYPICALLY BE REPRESENTED BY A COMPOSITION COMPRISING A SMALL AMOUNT OF AN OLEFIN AND/OR A VINYL COMPOUND, WATER, AND AN ORGANIC MEDIUM SUCH AS A LOWER-ALKANOL, WHICH IS IN PHYSICO-CHEMICAL EQUILIBRIUM STATE WITH A REACTION COMPOSITION COMPRISING AN OLEFIN AND/OR A VINYL COMPOUND, SAID ORGANIC MEDIUM AND A SMALL AMOUNT OF WATER.
