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-4335100-A 优先权日:1979-04-23 标 题:Method of inhibiting dextransucrase and oral compositions for use therein 发明人:ROBYT JOHN F; ZIKOPOULOS JOHN N 权利人:UNIV IOWA STATE RES FOUND INC 摘要:Dextransucrase synthesis of dextran from sucrose is inhibited by substituted sucrose compounds which have an inhibiting group bonded to the 5-position ring carbon. Oral compositions containing such substituted sucrose compounds can be used to control dextran formation in the mouth, and dextran comprises the principal component of dental plaque.
专利号:US-3954585-A 优先权日:1974-02-21 标题 :Synthesis of trifluoromethyl-substituted compounds 发明人:LAGOW RICHARD J; GERCHMAN LOIS L; JACOB ROBERT A 权利人:MASSACHUSETTS INST TECHNOLOGY 摘要:Trifluoromethyl-substituted compounds are formed in a corona discharge or glow discharge plasma of trifluoromethyl radicals from an organic trifluoromethyl source. A substrate possessing easily replaceable ligands such as halogen or carbonyl, is initially contacted either in the plasma and within a short distance from a downstream visible edge of the plasma or outside of the visible portion of the plasma and within a short distance from the downstream visible edge, to effect a substitution of the halogen or carbonyl ligand on the substrate with a trifluoromethyl radical without substantial decomposition of the substrate.
