Book Description
There are numerous criteria for measuring the growth and development of branches of chemistry. This valuable book illustrates a particular aspect of the growth of organosilicon chemistry. The extent of this field has developed so greatly in recent years that it now is desirable to reclassify parts to bring together hitherto frag mented and relatively disparate sections. This has been accomplished by the presently available large units which have been deSignated as "organosilicon heterocompounds. " Simplified expressions of such classification are structural units of the general type C - Si - heteroelement and heteroelement-C - Si, in which there are attached to the organosilicon moiety elements such as oxygen, nitrogen, metals, etc. This arrangement per mits the correlation of extensive material, which will be invalu able to chemists in many areas, both in and out of organosi- con chemistry. Because of the wealth of information, the authors are currently engaged in the preparation of companion volumes arranged on this general principle. The scope is broad, and includes material which will prove highly interesting and useful to those in academic, industrial, and governmental circles. There is not only a wide coverage of the literature generally, but the listings of patent references and of general reviews and books are among the most complete so far presented.

Book Description
One of the characteristics of the development of chemical science in the middle of the present century is the vigorous pro gress of the "third chemistry," which is often named now the chemistry of heteroorganic compounds. Then in the last decade, among specialists in this field there has been a marked increase in interest in heteroatomic organic derivatives of silicon, i. e. , heteroorganic silicon compounds. However, until recently this new class of chemical substances, which is extremely interesting theoretically and practically, has been without a single specialized monograph which systematizes and generalizes all progress in the heteroorganic chemistry of silicon. The first attempt in this direction was our book "Heteroorganic Compounds of Silicon" [42 (F), 17 (S) *], which appeared at the end of 1966 and was published as an English translation in the USA in 1969. However, as follows from its subtitle "Derivatives of Inorganic Elements," this mono graph could not cover the whole broad field of the chemistry of heteroorganic compounds of silicon. The main reason for this was above all the abundance and variety of original investigations of organosilicon derivatives of inorganic elements, which was un expected even to the authors themselves. As a result of this the planned length of the book compelled us to omit the sections on organosilicon compounds of phosphorus and sulfur, which had al ready been prepared for publication.

Book Description
A very large number of organo derivatives is formed by the Group IV ele ments silicon, germanium, tin, and lead. In comparing the general properties of these elements, Table 1. 1 shows that the first ionization energies decrease (though not in a regular way) with increase in size and atomic number, con sistent with the general increase in metallic character of the elements. Electro negativity values (which have been the subject of considerable controversy) show no clear trend. Although purely inorganic compounds of tin(n) and leaden) are well known, almost all organo Group IV derivatives show an oxidation state of IV. Bonds to carbon become weaker on passing from silicon to lead, as do the element-element bonds themselves. With any particular element M (M = Si, Ge, Sn, or Pb), there is a small decrease in bond energy in the order: M-Ph > M - Me > M - Et. Although accurate data for organo derivatives are lacking, strengths of bonds to other elements probably decrease in the order: M-F> M-O > M-CI > M-H ~ M-N ~ M-S ~ M-Br > M-I, while for a particular element X, the order is: Si-X > Ge-X > Sn-X > Pb-X. It is therefore understandable that reactions leading to Si-F, Si-O, or Si-CI bonds are especially favoured in a thermodynamic sense.

Book Description
Like so many of its kind, this textbook originated from the requirements of teaching. While lecturing on macromolecular science as a required subject for chemists and materials scientists on the undergraduate, graduate, and postgraduate levels at Swiss Federal Institute of Technology at Zurich (1960-1971), I needed a one-volume textbook which treated the whole field of macromolecular science, from its chemistry and physics to its applications, in a not too elementary manner. This textbook thus intends to bridge the gap between the often oversimplified introductory books and the highly specialized texts and monographs that cover only parts of macromolecular science. This first English edition is based on the third German edition (1975), which is about 40% different from the first German edition (1971), a result of rapid progress in macromolecular science and the less rapid education of the writer. This text intends to survey the whole field of macromolecular science. Its organization results from the following considerations. The chemical structure of macromolecular compounds should be independent of the method of synthesis, at least in the ideal case. Part I is thus concerned with the chemical and physical structure of macro molecules. Properties depend on structure. Solution properties are thus discussed in Part II, solid state properties in Part III. There are other reasons for discussing properties before syntheses: For example, it is difficult to under stand equilibrium polymerization without knowledge of solution thermody of the glass temperature, etc.

Book Description
Polysiloxanes are the most studied inorganic and semi-inorganic polymers because of their many medical and commercial uses. The Si-O backbone endows polysiloxanes with intriguing properties: the strength of the Si-O bond imparts considerable thermal stability, and the nature of the bonding imparts low surface free energy. Prostheses, artificial organs, objects for facial reconstruction, vitreous substitutes in the eyes, and tubing take advantage of the stability and pliability of polysiloxanes. Artificial skin, contact lenses, and drug delivery systems utilize their high permeability. Such biomedical applications have led to biocompatibility studies on the interactions of polysiloxanes with proteins, and there has been interest in modifying these materials to improve their suitability for general biomedical application. Polysiloxanes examines novel aspects of polysiloxane science and engineering, including properties, work in progress, and important unsolved problems. The volume, with ten comprehensive chapters, examines the history, preparation and analysis, synthesis, characterization, and applications of these polymeric materials.
