标题:Comparison Between Sime2 And Cme2 Spacers As σ-Bridges For Photoinduced Charge Transfer
摘要:The Potential Of Dimethylsilylene And Isopropylidene Sigma-Spacers As Bridges For Photoinduced Charge Transfer (Ct) In 4-Cyano-4'-(Dimethylamino)-And 4-Cyano-4'-Methoxy-Substituted Diphenyldimethylsilanes And 2,2-Diphenylpropanes Was Studied. Fluorescence Solvatochromism And Time-Resolved Microwave Conductivity Measurements Show That Upon Photoexcitation A Charge Separated State (D(.+)Sigma A(.-))* Is Populated In All Compounds. Excited State Dipole Moments For A Given Donor-Acceptor Combination Are,Irrespective Of The Bridge,Equal. The Ct States Of The Silanes Are However Lying At Lower Energies,Implying That The Presence Of Silicon Thermodynamically Facilitates The Ct Process. Cyclic Voltammetry Data Of Model Compounds Show That This Is A Consequence Of The Lowering Of The Acceptor Reduction Potential By The Silicon Bridge. It Was However Inferred From Radiative Decay Rates That The Electronic Coupling Between The Ct And Locally Excited States As Well As The Coupling Between The Ground And Ct State Is Larger For The Carbon-Bridged Compounds. As Shown By Both Solution And Solid State Electronic Spectra And Radiative Decay Rates,The Photophysics Of The D Sigma A Compounds Are Dominated By Intensity Borrowing Of The Ct Transitions From Transitions Localized In The D Sigma And Sigma A Chromophores.

标 题:Device for the synthesis of a polymer with extraction of a gaseous substance comprising a reaction chamber having at least one circular-cylindrical section
发明人：ZHU NING; STAMMER ACHIM; CLAUSS JOACHIM; KORY GAD
权利人:BASF SE
摘要:An apparatus for synthesis of a polymer with separation of a gaseous substance comprises a reaction space having an essentially circular cylindrical upper section which is bounded by two circular faces and one shell face and has a longitudinal cylinder axis, and a lower section, an inlet orifice disposed in a circular face or the shell face of the upper section, a first outlet orifice disposed in a wall of the lower section, a second outlet orifice disposed in the shell face of the upper section opposite the first outlet orifice, and a removal device which is disposed so as to be rotatable about the longitudinal cylinder axis and is in contact with both circular faces and the shell face. This apparatus can especially be used for performance of a process including the feeding of an oligomer melt into a reaction space through an inlet orifice, the polymerization of the oligomer melt to give a polymer melt, the removal of the polymer melt from the reaction space through a first outlet orifice of the reaction space, and the removal of a gaseous substance from the reaction space through a second outlet orifice of the reaction space, wherein deposits on at least one inner wall of the reaction space are removed by a removal device and transported into the oligomer melt.

摘要:Various embodiments provide random copolyimides that may possess the mechanical, thermal, chemical and optical properties associated with polyimides yet achieve a low energy surface. In various embodiments, the copolyimides may be prepared using a minor amounts of a diamino terminated fluorinated alkyl ether oligomer and a diamino terminated siloxane oligomer. The various embodiments include processes for making the copolyimides containing fluorine and silicon surface modifying agents and anisotropic coatings and articles of manufacture from them. Thus the coatings and articles of manufacture made with the copolyimides of the various embodiments may be characterized as having an anisotropic fluorine and silicon composition and low surface energy.

权利人:BASF SE
摘要:The present invention relates to a process for producing a surface-functionalized molding (oF) having a functionalized surface (fO). In this process a surface (O) of a molding (F) is brought into contact with a dienophile-containing solution (dL). The surface (O) comprises a polyamide (P) which comprises furan units. These furan units are able to react with the at least one dienophile present in the dienophile-containing solution (dL) to give the surface-functionalized molding (oF) having the functionalized surface (fO).

摘要:Various embodiments provide epoxy modified fluorinated urethane compositions that may provide desirable bulk mechanical properties of conventional coatings, adhesives, or structural matrix resins, while simultaneously exhibiting surface properties that may reduce surface contamination. Various embodiments provide formulations comprising epoxy modified fluorinated alkyl ether including urethane oligomer or polymer resins that may possess the requisite thermal, mechanical, chemical, and optical properties while achieving a low surface energy. In various embodiments, such resins may be prepared from random urethane oligomer compositions including fluorinated alkyl ether segments, in which the oligomers may be terminated with amino groups and subsequently reacted with epoxy including monomers or oligomers.
