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.

摘要:Described herein is a method to synthesize a perfluorinated allyl ether compound of formula (I) or a perfluorinated allyl amine compound of formula (II) Where Rf1 and Rf2 are (i) independently selected from a perfluorinated alkyl group comprising 1-7 carbon atoms, a perfluorinated aryl group comprising a 5- or 6-membered ring, or combinations thereof, and optionally comprising one or more catenated heteroatoms selected from N or O; or (ii) bonded together to form a perfluorinated ring structure having 4-8 ring carbon atoms, optionally comprising at least one catenated O or N atom; and Rf3 is a perfluorinated alkyl group comprising 1-3 carbon atoms. The resulting perfluorinated allyl ether compounds disclosed herein may be used in polymer synthesis.
