Transition metal-based polymer chemistry: a critical micro-review

Abstract

Abstract-This micro-review summarizes mainly recent (i.e. mostly later than 1995) and important developments in transition metal-catalyzed polymerization and their impact on polymer synthesis. It is not intended to be entirely comprehensive, yet will focus on signi cant improvements or interesting aspects in certain areas of polymer chemistry. For this particular reason, not all transition metal-based polymerizations will be fully covered. Instead, besides providing a 'snapshot' of the state of the art, it was a major intention to outline the main advantages and disadvantages of certain important polymerizations in a critical, yet hopefully objective way.

Synthesis, Characterization and Catalytic Investigation of Novel Polymeric Thiourea

“…Thioureas have been used in different areas, such as in the field of medicine, analytical chemistry and a wide spectrum of biological activities, fiber, inks, dyes, in mining engineering to collect copper and production of antioxidant and synthetic resins, and in order to produce herbicides and pesticides [13][14][15][16][17]. Furthermore, some of the thioureas, that contain transition metals, benzene and aryl (-CF 2 ) groups that are used as a catalyst for the Michael addition, polymerization, the Aza-Henry, Baylis-Hillman, Acyl-Pictet-Spengler and Nitro-Mannich reaction, are very important in industrial areas [18][19][20][21][22][23][24][25][26][27][28][29][30][31][32]. In the present work, the use of Ni(II) as a template agent for new polymerization techniques of thiourea was investigated and the reaction conditions optimized.…”
