标题:Synthesis And Transdermal Permeation-Enhancing Activity Of Carbonate And Carbamate Analogs Of Transkarbam 12
摘要:Transkarbam 12 (5-(Dodecyloxycarbonyl)Pentylammonium-5-(Dodecyloxycarbonyl)Pentylcarbamate,T12) Is A Highly Effective Skin Permeation Enhancer. In This Study,Ester Groups In The Molecule Of T12 Were Replaced By Carbonate And Carbamate Ones,Respectively. The In Vitro Permeation-Enhancing Activities Were Evaluated Using Porcine Skin And Compared With Those Of T12 And Previously Prepared Series Of Amide,Ketone,And Alkyl Analogs. According To The Activities And Behavior Of The Compounds In Donor Samples,Ester Group Is Essential For The Activity Of T12; Its Replacement Not Only Decreases The Enhancing Potency,But Is Likely To Change The Mechanism Of Action.

标 题 :One pot synthesis of urea (meth)acrylates
发明人：BESTGEN SEBASTIAN; BEYER SILVIA
权利人:EVONIK OPERATIONS GMBH
摘要:A one-pot synthesis of polymerizable and acyclic urea (meth)acrylates, preferably mono(meth)acrylates, can be performed via in-situ synthesis of urea alcohols or amines followed by direct reaction with a (meth)acrylate reactive diluent. The urea alcohol/amine is obtained from isocyanates and alcohols, amines, or hydroxyamines. Subsequently, the reaction with the (meth)acrylate reactive diluent takes place and the urea (meth)acrylate is directly obtained either in solution with the reactive diluent, or as a pure material after removal of the reactive diluent.

标 题:Synthesis of penta-substituted guanidines
发明人：RUETTIMANN KENNETH W; MCGHEE WILLIAM D; SOLODAR A JOHN
权利人:MONSANTO CO
摘要:The present invention is the novel synthesis of sterically hindered penta-substituted guanidines by a process in which (1a) an isocyanate is reacted first with a di-substituted amine or (1b) a urea is reacted with two moles of a mono-substituted amine to form a tri-substituted urea followed by (2) treatment of the tri-substituted urea with an activating agent before reacting with a second di-substituted amine in the presence of a base.

标 题 :Thiourethane polymers, method of synthesis thereof and use in fused filament fabrication printing
发明人：ELLSON GREGORY T; LUND BENJAMIN R; VOIT WALTER
权利人:BOARD OF REGENTS THE UNIV OF TEXAS; ADAPTIVE 3D TECH
摘要:A thermoplastic thiourethane polymer comprising a sequential chain of a first type of monomer covalently bonded to a second type of monomer via thiourethane linkages. The first type of monomer includes two or more thiol functional groups and the type of monomer includes two or more isocyanate functional groups. The first and second types of monomers are polymerized together in an anhydrous aprotic solvent-dissolved anionic step-growth polymerization reaction that is catalyzed by a non-nucleophillic base having a pKa greater than 7.

标题 :Synthesis of linear polyoxazolidinones using uretdiones as diisocyanate component
发明人：QUELL AGGELIKI; THOMAS HANS-JOSEF; ELING BEREND
权利人:BASF SE
摘要:A process for preparing a thermoplastic polymer involves reacting at least components (a) to (b), in the presence of a catalyst composition (c). Component (a) is an isocyanate composition containing at least one uretdione diisocyanate (a-i), and component (b) is an epoxide composition containing at least one diepoxide (b-i). The catalyst composition (c) contains at least one ionic liquid (c-i), preferably selected from 1-ethyl-3-methyl imidazolium bromide, 1-benzyl-3-methyl imidazolium chloride. 1-butyl-1-methylpiperidinium chloride, 1-ethyl-2,3-dimethylimidazolium bromide, 1-(2-hydroxyethyl)-3-methyl imidazolium chloride, butyl-1-methylpiperidinium acetate, or mixtures of two or more thereof. A thermoplastic polymer obtained or obtainable from the process is useful for the preparation of a fibre or a molded article or as a modifier for another thermoplastic material.

摘要:A semi-crystalline thiourethane polymer. The semi-crystalline thiourethane polymer comprises a sequential chain of a first type of monomer covalently bonded to a second type of monomer via thiourethane linkages. Each of the first type of monomer includes two or more thiol functional groups and each of the second type of monomer includes two or more isocyanate functional groups. The first and second types of monomers are polymerized together in an anionic step-growth polymerization reaction that is catalyzed by a non-nucleophillic base having a pKa greater than 7, produced by photo-initiated decomposition of a photolatent base. A method of synthesizing, and polymer jetting and stereolithography methods of manufacturing a polymer part, are also disclosed.

摘要:The present invention relates to polyoxazolidinone compounds, a method for the production of polyoxazolidinone compounds, comprising the step of reacting a biscarbamate compound with a bisepoxide compound in the presence of a mono-carbamate, a mono-isocyanate and/or a mono-epoxide compound as chain regulator and a suitable base having a pK b value of ≤9 as catalyst. The invention further relates to the use of polyoxazolidinone compounds with high thermal stability.
