A process for the production of alkyl and/or alkenyl ethers with terminal alkyl groups involves reacting alcohols of formul R<1>O-(CH2CH2O)n-(CH2CH(CH3)O)m-H (I) with dialkyl carbonates of formula R<3>OCOOR<4> (II), in which R<1> = optionally unsaturated, linear or branched 6-...
Our results clearly demonstrate how the end-capping groups modify the chromatographic properties of adsorbents. Differences between solvent adsorption mechanisms are also discussed. Adsorption of acetonitrile is governed by hydrophobic effects whereas methanol is adsorbed by the organic ligand by a ...
In order to synthesize telechelic poly(tetrahydrofuran) [poly(THF)] with benzoic acid terminal groups (9), the reaction of bifunctional living cationic poly(THF) initiated by trifluoromethanesulfonic anhydride with lithium or sodium salt of methyl p-hydroxybenzoate was performed in THF solvent at 0...

Three amine-functionalized 1,1-diphenylethylene (DPE) derivatives (DPE-(NMe 2 ) 2 , DPE-NMe 2 and DPE-SiH/NMe 2 ) were used to study the end-capping reactions of poly(styryl)lithium (PS-Li) for investigating the effect on end-capping of electron-donating groups in DPE structures. In...
Endcapping a water-soluble and non-peptidic polymer having two hydroxyl groups, e.g., polyoxyethylene glycol, to form a blend of mono-ols, diols, and diendcapped polymer; ion exchange purifying to obtain only the mono-ol; protective coatings for proteins; medical equipment; biopolymer carrier;...
aThe integer n has a value of about 25 to 100, or greater. It will be understood by those skilled in the art that, during reaction and prior to end-capping, the polymer chain has terminal --SO2 ---CF2 groups. 整数n有价值的大约25到100或者更加伟大。 它将由那些技术熟练者了解,在反应期...
