Abstract
The present invention relates to a method for manufacturing of partially fluorinated polymers, notably vinylidene fluoride (VDF)-based polymers, in emulsion polymerization, and to a polymer obtained from said method.
Claims20
A method for the synthesis of a partially fluorinated polymer (P) comprising recurring units derived from 1,1-difluoroethylene, said method comprising polymerizing 1,1-difluoroethylene, optionally in the presence of at least one further (per)fluorinated monomer (MF), in an aqueous emulsion in the presence of a redox-initiating system (R) comprising at least one organic radical initiator and at least one composition (CS) comprising at least one compound (S) bearing at least one sulfinic acid group.
