Adeli Abstract Functionalized poly(ethylene glycol) (PEG) containing four chloride end functional groups (PEG-Cl4) was synthesized through reaction between cyanuric chloride and PEG-(OH)2. Chloride end functional groups of PEG-Cl4 were able to initiate the ring opening polymerization of 2-ethyl-2-oxazoline and star copolymers containing a PEG core, and poly(2-ethyl-2-oxazoline) (POX) arms were obtained. Polymerization was quenched using diethanolamine, and star copolymers containing hydroxyl end functional groups (PEG-POX-OH) were obtained. ,-Caprolactone was then polymerized using the hydroxyl end functional groups of star copolymers and amphiphilic linear-dendritic copolymers containing PEG and POX, and poly(caprolactone) (PCL) blocks were synthesized. Linear-dendritic copolymers were able to load the organic and inorganic guest molecules. Application of host-guest systems such as nanocatalyst for Heck chemical reaction was also investigated. © 2009 Wiley Periodicals, Inc. J Appl Polym Sci, 2009 [source] Triaminotriazines,photophysical investigations of a porphyrin-appended triazine receptor with a naphthalene diimide guest,JOURNAL OF PHYSICAL ORGANIC CHEMISTRY, Issue 8-9 2006Kenneth P. Ghiggino Abstract A modular synthetic approach to preparing a family of triaminotriazine receptors bearing porphyrin chromophores is described. The porphyrin-appended triaminotriazines are prepared in a stepwise manner employing either cyanuric chloride or fluoride and 5-(4,-aminophenyl)-10,15,20-triphenylporphyrin in the first step. Reaction of the porphyrintriazine with excess 1-pentylamine leads to a triazine core programmed for three-point hydrogen bonding. Addition of a complementary naphthalene diimide yields a supramolecular donor,acceptor dyad. Photophysical studies in CH2Cl2 solvent show efficient quenching of porphyrin fluorescence within the dyad, consistent with an electron transfer process. Copyright © 2006 John Wiley & Sons, Ltd. [source] Dendrimers based on [1,3,5]-triazinesJOURNAL OF POLYMER SCIENCE (IN TWO SECTIONS), Issue 11 2006Mackay B. Steffensen Abstract A comprehensive and chronological account of dendrimers based on [1,3,5]-triazines is provided. Synthetic strategies to install the triazine through cycloaddition, cyclotrimerization, and nucleophilic aromatic substitution of cyanuric chloride are discussed. Motivations and applications of these architectures are surveyed, including the preparation of supramolecular assemblies in the solution and solid states and their use in medicines, advanced materials, and separations when anchored to solid supports. © 2006 Wiley Periodicals, Inc.

The test is based on the measurement of the electrophoretic mobility of the microspheres with immobilized H. pylori antigens. The electrophoretic mobility of these microspheres depends on the concentration of the antibodies against H. pylori in suspending medium. Particles with hydrophilic polyglycidol in the surface layer were used for the test. The microspheres were obtained by an emulsifier-free emulsion copolymerization of styrene and , - tert -butoxy- , -vinylbenzyl-polyglycidol macromonomer (,=,220 nm, diameter polydispersity factor ,=,1.02). Activation of polyglycidol hydroxyl groups with cyanuric chloride allowed for covalent immobilization of H. pylori antigens. The fraction of H. pylori not specifically adsorbed onto the microspheres was negligible. Changes of the electrophoretic mobility of the microspheres with the surface concentration of the covalently immobilized H. pylori antigens ,,=,(1.6,±,0.3),·,10,3 g m,2 were suitable for the detection of the antibodies in the sera of patients with titer in the range (determined by the indirect ELISA test) from 1:500 to 1:32,000.

Properties of amine modifiers for unsaturated polyester resins are presented. The modifiers were incorporated into resins at the polycondensation stage. [source] High affinity, high efficiency fibre-reactive dyesCOLORATION TECHNOLOGY, Issue 4 2006Brent Smith A straightforward two-step method for modifying commercial dichlorotriazine-based fibre-reactive dyes prior to their use in the dyeing process can greatly improve affinity and fixation efficiency on cotton, and reduce the salt requirements. The modification used in this study involved prereacting the commercial dyes with either cysteine or cysteamine followed by reaction of the resulting intermediate with cyanuric chloride. Cotton fabric dyed with the modified dyes had technical properties that were essentially equal to those obtained from the unmodified commercial dyes. [source] | |||||||||||||
