This book gives a comprehensive coverage of the synthesis of polymers and their reactions, structure, and properties. The treatment of the reactions used in the preparation of macromolecules and in their transformation into cross-linked materials is particularly detailed and complete. The book also gives an up-to-date presentation of other important topics, such as enzymatic and protein synthesis, solution properties of macromolecules, polymer in the solid state. The content and presentation of Professor Vollmert s book is more encompassing than most existing treatises, and its numerous figures and tables convey a wealth of data, never, however, at the expense of intellectual clarity or educational value. 

In situ synthesis is extremely sensitive to a wide variety of factors, including the composition of the synthesis solution, support material, contact between the support and gel, as well as synthesis conditions (i.e., temperature, duration, sol... 

Abstract The Zr (Ti)-Si-Al HDN Catalytic Materials have been synthesized rapidly with a new route heated by microwave. The synthesis conditions such as synthesis temperature, microwave oven pressure, pH value of synthesis solution and raw material were examined by experimentation. The thermostability, pore volume, surface area, surface Si/Al and hydrodenitrogen activity of the synthesis samples were also characteristiced. 

The experimental results show that the optimal synthesis conditions are as follow synthesis temperature =80°C, microwave oven pressure =0.2MPa, synthesis solution pH =10, calcination temperature =500°C. 

The synthesis solution pH value is not only influencing on surface area of the synthesis samples, but also changes their structure.

A third possibility for the synthesis of nanomaterials in constrained volumes is the use of molds (Figure 3.1c). Advantages of this method include its simplicity, versatility, and precise control over the shape of the solid, even with intricate forms. An elegant example of this strategy is the preparation of zeolites which precisely replicate the complex microstructure of wood. To do this, Dong et al. [43] infiltrated a zeolite synthesis solution into a wood sample. After the necessary hydrothermal treatment, and subsequent calcination to remove the template as well as the wood, a zeolitic structure was obtained that reproduced with full detail and fidelity the wooden sample used as a mold.

Asymmetric star polymers are megamolecules [1] emanating from a central core. In contrast to the symmetric stars very little was known, until recently, about the properties of the asymmetric stars. This was due to the difficulties associated with the synthesis of well-defined architectures of this class of polymeric materials. The synthesis, solution and bulk properties, experimental and theoretical, of the following categories of asymmetric stars will be considered in this review ...
