J.M. Zeigler and F.W.G. Fearon (Eds.), Silicone Based Polymer Science. A Comprehensive Resource, Advances in Chemistry Series No. 224

ACS Washington, DC, 1989, $129.95. This book indeed is a comprehensive resource for information on silicone-based and related polymers. The text consists of a total of 42 chapters, including two review chapters on fundamentals and chapters on dimensional characteristics of siloxane polymers, new synthetic procedures for polysilanes and related polymers, preceramic polymers and other silicone-based polymers. The book is mainly concerned with aspects of organic and synthetic chemistry and polymer physical properties. A number of characterization methods are described in the text; these include thermodynamic properties, NMR spectroscopy, chromatographic separation, X-ray, Raman spectroscopy, morphological evaluation using TEM and laser desorption electron-impact mass spectrometry. Major portions of the text are published frequently in the polymer literature. However, the inclusion of attractive concepts and innovative research ideas from the subject areas of polysiloxane IPNs, functionalized organosiloxane and hybrid materials through a sol-gel approach and polycarbosilane is noteworthy. Although one chapter focuses on the surface properties of silicone based polymers, other chapters only detail bulk polymer properties. Interfacial phenomena have not been addressed and no chapter deals with the characteristics of and distinction between the surface and the bulk region of these polymers. This reviewer expected to read about hydrophilic component polysiloxanes and silicone-based hydrogels, but found the book lacking information in these areas. Since silicone-based polymers are rather well known to polymer scientists, these readers may expect to see novel ideas, new syntheses and future applications for these polymers, but they are not present in the text. A more extensive overall

review and descriptions of future trends would have enhanced the book. In conclusion, this text is useful in understanding the current status of organic-chemistrybased silicone polymer chemistry. However, the book is weighed down by a content too broad in its scope and lacks many important subject areas and aspects, such as interfacial and surface properties and potential applications for medical, pharmaceutical, electronic and other fields. The book is still useful as a good reference to siliconebased polymers. SUNG WAN KIM

Multiphase Biomedical Materials, edited by T.

Tsuruta and A. Nakajima, VSP, Utrecht, The Netherlands, 1989, $12 1.OO. This book contains selected contributions from research groups supported by the Japanese Ministry of Education, Science and Culture under the Special Research Project ‘Design of Multiphase Biomedical Materials’. The multiphase biomedical materials examined in the eleven chapters of the book are classified as: (i) Materials with microdomain structures (such as block and graft copolymers for non-thrombogenic materials and cell-specific adsorbents); (ii) Materials containing liquid components (such as polysaccharidecoated liposomes for drug delivery towards specific tissues); (iii) Hybrid-type materials with biological components (such as hybrid organs of hepatocytes into collageneous matrices or synthetic polymer-protein hybrids for the immunoreactivity reduction of protein drugs); and (iv) Inorganic and metallic materials (such as glassceramics and metallic alloys for hard tissue replacement ) .
