| 摘要 |
<p>The present invention concerns a method for the dispersed phase polymerisation of halogenated vinyl compounds, having the formula RbRcC=CX1X2, where: X1 = F or CI, X2 = H, F or CI, each of Rb and Rc separately represents: - H, CI, F; or - an alkyl group, preferably chlorinated and/or fluorinated, and more advantageously perchlorinated or perfluorinated , comprising a step (E1) wherein said monomers are introduced into an aqueous phase together with - at least one source of free radicals; and - at least one reactive stabiliser comprising a polymer chain and a thiocarbonylthio-S group (C=S)-, said polymer chain comprising non-(N-vinyl lactam) monomer units.</p> |
