Zustand: Hervorragend. Zustand: Hervorragend | Sprache: Englisch | Produktart: Bücher | Today¿s requirement of novel polymers with improved property has been expanding with time and it can be said to be endless. The world would have appeared totally different without artificial fibers, plastics, elastomers etc. Though introduced very late, polymers occupy a major place and pivotal position in our materials map today.In application prospects, performance and versatility in property that can hardly be occupied by any other kind of materials. High performance polymers carry huge demand in the routine activities of human life and extended to large industrial application. This is possible only because of their low production cost and easier availability of the raw materials.A literature survey reveals that the polymers based on s-triazine moiety and their derivatives have been extensively used since last few years.Polymers containing s-triazine ring in the main chain have excellent heat resistance and several are commercially available as high-performance engineering plastic materials. This book contains synthesis, characterization and physico-chemical properties of polycyanurates and homopolyesters containing s-triazine ring in the main chain. …

Zustand: Hervorragend | Sprache: Deutsch | Produktart: Bücher | 1,2,3-Oxadiazol-haltige Sulfonamid-Derivate sind in der medizinischen Chemie für die Untersuchung der biologischen Anwendungen nützlich. Diese Derivate besitzen verschiedene biologische Aktivitäten wie antibakterielle, antitumorale, antimykotische, antimalaria-, antiparasitische, analgetische, antioxidative und entzündungshemmende Wirkung. Daher haben wir uns auf verschiedene biologische Aktivitäten konzentriert. Die Struktur der synthetisierten Verbindungen wurde durch Elementaranalyse, IR und 1H-NMR-Spektraldaten charakterisiert.…
