The "Polymer Yearbooks" provide reviews of Japanese and Russian polymer science not otherwise readily available in English. A desk reference interest to polymer scientists, they contain reviews covering topics in polymer synthesis, degradation, renewable polymer sources, drug release, thermodynamics of polymers under shear, and more. The books also contain lists of publications in polymer science and their editors are listed, together with information such as standard abbreviations and trade names. There are summaries of physical, chemical and mathematical data along with definitions of terms in polymer science. This volume also contains state-of-the-art Japanese research presented in the annual Spring and Fall meetings of the Japanese Polymer Science Society. The aim of this section is to make information on the progress of Japanese polymer science, and on topics of interest to polymer scientists in Japan, more easily available worldwide.
