More Information
Summary:The object of the present invention is to provide a fluorine-containing diblock copolymer having good water and oil repellency by using, as a raw material, a fluorine-containing (meth)acrylic ester having low bioaccumulation potential. The fluorine-containing diblock copolymer of the present invention is producedby: (process A) a process for producing a fluorine-containing diblock copolymer by polymerizing a fluorine-containing (meth) acrylic ester represented by the following formula (1) in the presence of a trithiocarbonic ester compound and a radical polymerization initiator and then polymerizing a non-fluorine vinyl-based monomer, or (process B) a process for producing a fluorine-containing diblock copolymer by polymerizing a non-fluorine vinyl-based monomer in the presence of a trithiocarbonic ester compound and a radical polymerization initiator and then polymerizing a fluorine-containing (meth) acrylic ester represented by the following formula (1).
