ADDITION POLYMERISATION |
摘要 |
<p>A method of producing a polymer comprises the steps of forming a heterogeneous reaction mixture comprising at least one addition polymerizable monomer, a supercritical fluid, and a stabilizer, wherein the stabilizer comprises a chain which is soluble in the supercritical fluid and functional end-group which is not polymerizable by a free-radical mechanism, and polymerizing said at least one monomer in the reaction mixture. In a preferred system for polymerizing acrylic monomers, the fluid comprises supercritical carbon dioxide and the stabilizer comprises an acid-functionalized perfluoropolyether.</p> |
