In the electronic industry, there is a need for materials of different electrical conductivities ranging from the semi-conducting to the conducting region. In addition the materials should be easily processable and stable . The synthesis of new electrically conducting polymers with different chemical structures provides an efficient method for the introduction of new materials with the qualifications described above. Furthermore, knowledge of the electrical behavior of a great member of polymers with various chemical structures enables us to understand the relationship between the electrical...

New method for measured the hypertension drugs by one run in HPLC. Two cross like polymer were prepared. first polymer was synthesized by condensation reaction between glycerol triethanol amine with maleic anhydride. The second polymer was synthesized by addition polymerization of free radical for acrylamide, bisacrylamide with ammonium persulphate and TEMED. The products and used as stationary phase for HPLC. This stationary phase has been packed into stainless steel column. The chromatographic performances of the newly packed columns are characterized.N,H,Ќ and α were measured. Amiloride,...

The first part of this work emphasizes on the synthesis, structural characterization, and liquid crystalline and luminescent properties investigations of novel azomethine and thiophene azomethine polymers. The second part involves, studying the opto-electronic properties of the materials under investigation. Light emitting diodes based on the polymers under study as emitting layer have been prepared. The diode device's characteristics such as current, turn on voltage, and ideality factor have been measured for all PLED device. This book would be of benefit for those who are interested in...
