| titleOfInvention | Polymerization process |
| abstract | The invention pertains to a polymerization process comprising polymerizing at least one fluorinated monomer in the presence of a radical initiator and a surfactant in a polymerization medium comprising carbon dioxide to provide a polymer product, characterized in that the surfactant is a functional (per)fluoropolyether, which is a polymer comprising recurring units (R1) and at least one functional group comprising a heteroatom other than fluorine, said recurring units comprising at least one ether linkage in the main chain and at least one fluorine atom (fluoropolyoxyalkene chain). n It has been surprisingly observed that the polymerization advantageously occurs without fouling or deposit formation on the reactor walls and the product is obtained as dry powder having improved morphology (percentage of organized structures, i.e. of particles of regular shape). |
