Title:
Control free radical copolymerization of trifluoro ethylene
Document Type and Number:
Japanese Patent JP6212542
Kind Code:
B2
Abstract:
The invention concerns a method for preparing block copolymers, comprising a step of controlled free-radical copolymerisation of trifluoroethylene with at least one additional monomer, different from trifluoroethylene, in the presence of a chain transfer agent, said chain transfer agent being a xanthate compound, a trithiocarbonate compound or a monoiodide compound. The invention also concerns the block copolymers likely to be obtained by this method.
