摘要:Methods for the synthesis of CTFE-based block copolymers through iodine transfer polymerization are disclosed. In an exemplary embodiment, a method includes reacting a fluoromonomer “Mâ€? with a chain transfer agent of the formula X—Y or Y—X—Y, wherein X represents a C 1 -C 3 hydrocarbon, a C 1 -C 6 hydrofluorocarbon, C 1 -C 6 hydrochlorofluorocarbon, or C 1 -C 6 fluorocarbon and Y represents iodine or bromine, in the presence of a radical initiator, to form a macro-initiator of the formula: X-poly(M)-Y or Y-poly(M)-X-poly(M)-Y, wherein poly(M) represents a polymer of the fluoromonomer. The method further includes reacting the macro-initiator with chlorotrifluoroethylene (CTFE) in the presence of a radical initiator to form a diblock or a triblock CTFE-based block copolymer of the formula: X-poly(M)-block-poly(CTFE) or PCTFE-block-poly(M)-X-poly(M)-block-PCTFE.

标 题 :Manganese catalyzed photopolymerization of fluorinated monomers
发明人：ASANDEI ALEXANDRU D
权利人:UNIV CONNECTICUT
摘要:The disclosure discloses initiating systems for the radical polymerization of alkenes, and especially fluorine substituted alkenes. The polymerization is catalyzed by a metal carbonyl, preferably manganese carbonyl. The polymerization is initiated directly from alkyl halides at room temperature under visible white light. The polymers also allow the synthesis of block copolymers. The process comprises polymerizing at least one alkene monomer in the presence of a halide radical initiator, carbonyl catalyst and a solvent, under reaction conditions and for a time sufficient to polymerize the at least one alkene monomer to form a polymer. The present disclosure provides a method for living polymerization of alkene monomers which provides a high level of macromolecular control over the polymerization process and which leads to uniform and controllable polymeric products. This disclosure also provides a method for activating any halide (Cl, Br, I) chain ends of such polymers for the synthesis of block copolymerizations.
