标题:Effects Of Addition Gases On The Ir Multiphoton Dissociation Of Haloethanes
摘要:添加气体对cclf2Ch2Cl的红外多光子解离(irmpd)速率的影响进行了研究.使用了he,Cf4,Cf3Cdbrcl和ccl2Cf2作为添加气体,并测量了irmpd产率与添加气体摩尔分数的关系.结果揭示了分子碰撞在激发过程中的重要作用,反应速率由两种碰撞诱导过程的竞争决定,其中一种抑制反应,而另一种增强反应.对于961.9 Cm-1的辐照,两种效应均被清晰观测到,而对于1023.2 Cm-1的辐照,后者效应似乎较弱.结果还表明,添加cf4或he总是降低反应速率.我们得出结论,谐波性瓶颈的松弛通过共振的振动能量转移对该分子的irmpd至关重要.

标题 :Fluorinated elastomers with low glass transition temperatures based on vinylidene fluoride and free of tetrafluoroethylene or siloxane group
发明人：AMEDURI BRUNO M; ARMAND MICHEL; BOUCHER MARIO; BOUTEVIN BERNARD L
权利人:HYDRO QUEBEC
摘要:The present invention describes synthesis of new fluorinated elastomers presenting very low glass transition temperatures, a good resistance to bases, petroleum and fuels and good properties for forming. These elastomers contain, by way of example, from 90 to 50 mole % of vinylidene fluoride (VDF) and from 10 to 50 molar % of perfluoromethyl vinyl ether (PMVE). In this precise case, they are prepared by radical copolymerisation of VDF and with PMVE in presence of various organic initiators such as for example the peroxides, the peresters or the diazo compounds.

摘要:The present invention describes the synthesis of new sulforated fluorinated elastomers having very low glass transition temperatures (Tg), a good resistance to bases, oils and fuels and good properties of workability. These elastomers contain, by way of example, from 80 to 60 mole % of vinylidene fluoride (VDF) and 20 to 40 mole % of perfluoro(4-methyl-3,6-dioxaoct-7-ene) sulfonyl fluoride (PFSO2F). In this case, they are prepared by radical copolymerisation of VDF and PFSO2F in the presence of different organic initiators, for example, peroxides, peresters or diazo compounds.

摘要:alpha,beta,beta-Trifluorostyrene and derivatives thereof synthesized in two steps from 1,1,1,2-tetrafluoroethylene. In the first step, 1,1,1,2-tetrafluoroethylene is reacted with a base, a metal salt such as zinc chloride and an optionally amine to form a trifluorovinyl metal complex. In the second step, the trifluorostyrene or derivative is obtained by reacting the trifluorovinyl metal complex with an aryl transfer agent such as, for example, an aryl triflate or an aryl halide, in the presence of a metal catalyst and optionally a coordinating ligand. Both steps may be carried out in one reactor.
