专利号:US-9512250-B2 优先权日:2012-02-23 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.

Such compounds may function by inhibiting sex steroid synthesis (both estrogen and androgen synthesis) and/or by antagonistically blocking androgen receptors.
