(1) Condensation polymers are synthesized by the polyaddition without harmful waste by- products: this is a synthetic advantage in polymer chemistry and industrial processes from the viewpoint of atom economy, as proposed by Trost.39 (2) The polymerization proceeds by forming reactive chloromethyl ...
Process for the synthesis of organic nitrogen compounds comprising the reaction of carbon monoxide, with at least one amine comprised in a reaction mixture comprising a base of selenium and a pyridine substituted. < / p & gt; & lt; p & gt; the process is particularly well to the synthesis...
Consequently, biodegradable polymers are the topics of much research. Biodegradable polymers can be mainly classified as agro-polymers (starch, chitin, protein…) and biodegradable polyesters [polyhydroxyalkanoates, poly(lactic acid)…]. These latter, also called biopolyesters, can be synthesized from...
Resorbable, implantable bioelectronic devices are emerging as powerful tools to reliably monitor critical physiological parameters in real time over extended periods. While degradable magnesium-based electronics have pioneered this effort, relatively sho
A series of porous polymers poly(styrene-divinylbenzene) was synthesized by the polymerization of 9 : 1 (v/v) styrene/divinylbenzene using high-internal-ph... WF Xu,B Rui,FA Zhang - 《Journal of Polymer Research》 被引量: 14发表: 2014年 Synthesis of microsphere-loaded porous polymers by...
Polymers are synthesized by joining small molecules into large ones. But most of these monomeric molecules are perfectly stable as they are, so chemists have devised two general methods to make them react with each other, building up the backbone chain as the reaction proceeds. Condensation-elimina...
The synthesis of cyclic polymers and the functionalities arising from their unique shapes, namely topology effects, are reviewed. The electrostatic self-assembly and covalent fixation (ESA-CF) process was used in conjunction with click chemistry and with olefin metathesis to construct selectively a ...
Low-viscosity liquid epoxidized aromatic hyperbranched polymers are synthesized by the reaction between epichlorohydrin (ECH) and carboxy-end hyperbranched... D Zhang,D Jia - 《European Polymer Journal》 被引量: 135发表: 2006年 Effects of High Energy Radiation on Polymers III. Viscosity It was know...
Soft pressure sensors drift under prolonged high stress because of the creep of soft materials, which causes inaccurate measurements. Now, through molecular-level design, a leakage-free and creep-free polyelectrolyte elastomer is synthesized, and an iontronic sensor using the polyelectrolyte elastomer sho...
LCB polymers are synthesized according to inventive processes, then weighed and analyzed by a combination of analytic methods, including nuclear magnetic resonance (NMR), differential scanning calorimetry (DSC) and gel permeation chromatography with three detectors (GPC-triple detectors), including reflectio...
