摘要:比解离的 Eto-更具反应性.7A-I 与解离的 Eto 和离子对 Etok 反应的 Hammett 图表现出极好的线性相关性,分别与 x = 3.00 和 2.47.已建议反应通过逐步机制进行,其中离去基团的离开发生在 Rds 之后.Ketok/keto 比率与 x 常数的相关性表现出极好的线性度,斜率为-0.53.得出的结论是,离子对 Etok 通过增加反应中心的亲电性而不是通过提高离去基团的离核性来催化反应.

摘要:A method for a synthesis of a polymer containing multiple epoxy groups includes steps of: under protection of nitrogen or argon, with a photosensitive free radical initiator under an ultraviolet light irradiation, initiating a mixture of a dithiol compound and alkynyl glycidyl ether or other alkynyl-containing compounds to proceed a thiol-yne polymerization, so as to obtain the polymer. The number of the epoxy groups is able to be adjusted through changing a type of a dithiol monomer, a mixing ratio of the dithiol monomer, and a mixing ratio between the alkynyl glycidyl ether and other alkynyl compounds. The present invention has advantages of: fast reaction, convenient process, easy post-processing, a large number of the epoxy groups, and adjustable and controllable content. The obtained polymer has a wide potential application in fields of coating, adhesive, ink, encapsulating material, resin for composite material, additive, high performance material, function material, and so on.

权利人:XOLO GMBH
摘要:The present invention relates to spiropyrans and process for the manufacture of them. In particular, a method is provided to exchange the indole and salicylaldehyde part of a spiropyran in a reversible reaction. The method is used for the synthesis of dual color photoinitiators with specific substituents and substitution patterns, which result in improved dual color volumetric printing (xolography). Furthermore, a process for locally polymerizing a starting material by dual color photopolymerization is disclosed.

摘要:A non-aqueous single pot synthesis of [ 18 F]SFB is set forth. The [ 18 F]SFB produced with this method is then used, for example, to label a peptide or an engineered antibody fragment (diabody) targeting human epidermal growth factor receptor 2 (HER2) as representative examples of labeled compounds for use as an injectable composition to locate abnormal tissue, specifically tumors within an animal or human using a PET scan.

标题 :Synthesis of photoreactive polymeric binders

摘要:A photoreactive binder that may be used to enhance photospeed in either conventional plates or on-press developable lithographic printing plates. Briefly, a polymer of m-isopropenyl- alpha , alpha -dimethylbenzyl isocyanate is derivatized for vinyl group reactivity by reacting the isocyanate groups thereof with hydroxyalkyl acrylate. The resulting photopolymeric binder provides significantly higher photospeed than the non-reactive binder currently utilized in the production of conventional printing plates. The resulting lithographic printing plate also shows better durability (as manifested by longer run-length) and is more easily developed by the microencapsulated developers utilized in the present invention. As to the preparation of the photoreactive binders, the application discloses a method of copolymerizing m-isopropenyl- alpha , alpha -dimethylbenzyl isocyanate (m-TMI) through complexation with an electron-deficient monomer such as maleic anhydride to accelerate free radical copolymerization with other monomers, and thus, provides greater monomer-to-polymer conversion. Use of the resulting product in the photoresist of a lithographic printing plate improves its adhesion to an underlying substrate.
