High historical background

The opening chapter gives some historical background to the investigation of high-energy processes. The discussions in the subsequent chapters proceed from current studies in the gas phase, to examination of liquid-phase techniques, and finally to applications in the solid state. The final chapters provide a perspective on current and future industrial applications of the field. 

Bioinorganic chemistry was extended in Japan by amalgamating solution chemistry, coordination chemistry and biochemistry. From such a historical background, biochemistry in Japan has still a strong interrelationship with solution chemistry. Everybody recognizes a high activity of bioinorganic chemistry in Japan. 

The direct condensation polymerization of aromatic diacids and diphenols has not been demonstrated to be a feasible route for obtaining high molecular weight polyarylates. However, three monomer variations have been shown to yield acceptable high molecular weight products. These variations include the acid chloride process in which the aromatic diacid is first reacted to form the acid chloride (e.g. phosgene) followed by condensation with the diphenol. The second route involves the preparation of the diphenyl ester of the aromatic diacid followed by reaction with the diphenol. The third process involves preparation of the diacetate of the diphenol followed by reaction with the aromatic diacid. The historical background of these reaction schemes will be discussed.
