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.

专利号:US-6329470-B1 优先权日:1999-09-30 标 题:Fluorocarbon end-capped polymers and method of synthesis 发明人:GARDELLA JR JOSEPH A; HICKS JR WESLEY; KOLOSKI TIMOTHY; LOSITO ILARIO; LEE WON-KI; VARGO TERRENCE G 权利人:UNIV NEW YORK STATE RES FOUND 摘要:The present invention provides novel surface modified biodegradable polyesters having fluorocarbon chains at the terminal end of the polyesters. The compounds of the present invention are obtained by the addition of fluorocarbon chains at the surface of the polyester. Any commonly used polyester material can be used in the present invention; however, polyglycolic or polylactic acids or co-polymers thereof are preferred.
专利号:US-3963734-A 优先权日:1971-09-17 标 题:Lower alkylsulfonyl 2-amino, 3-nitro pyridines 发明人:DOHERTY GEORGE O P; FUHR KENNETH H 权利人:LILLY CO ELI 摘要:Substituted 1-hydroxy-2-(1,1-difluoroalkyl)-1H-imidazo-(4,5-b)pyridine compounds useful as herbicides; and intermediates useful in the synthesis of these compounds. In addition to exhibiting herbicidal activity, the substituted 1-hydroxy-2-(1,1-difluoroalkyl)-1H-imidazo(4,5-b)pyridine compounds are of low mammalian toxicity.
