Ink analysis of the writing on each page of the agreement and the notes, showed that the same ink formulation was used on the documents. Figure 6 shows the similarity among these chromatograms. In addition, the findings revealed that the documents could not have been in existence in 1958, because a unique dye identified in the ink was first synthesized by Ciba Chemical Corp. in 1959 and the ink formulation was not produced until 1960.

The chemical industry manufactures a large number of antioxidants (qv) as well as uv stabilizers and their mixtures with other additives used to facilitate resin processing. These companies include American Cyanamid, BASE, Ciba—Geigy, Eastman Chemical, Elf Atochem, Enichem, General Electric, Hoechst—Celanese, Sandoz, and Uniroyal, among others. The combined market for these products in the United States exceeded 900 million in 1994 and will reach 1 billion in the year 2000. 

In 1993 the five principal producers of organic pigments in the United States were BASF Cotp., Ciba-Geigy Cotp., Hoechst Celanese Cotp., Miles Inc. (Bayer), and Sun Chemical Cotp.

The option most promising today iavolves use of a new family of polymers, the so-called high temperature scale-control chemicals. These are compounds that, added ia 3—8 ppm, lead to lattice distortioa and the formation of a nonadhering scale. Belgard (CIBA-GEIGY) was the first compound...

Commercial BMI Resins. Since the late 1960s, bismaleimide resins have been commercially available. The first company in the marketplace was Rhc ne Poulenc Chimie, Erance. Several others, Technochemie, Germany CIBA GEIGY, Switzerland DSM, The Netherlands, BASE, West Germany Mitsubishi Gas Chemicals and MitsuiToatsu, both of Japan Reichhold and Polyorganics from the United States and Shell Chemical Company, United States (through the acquisition of Technochemie by Deutsche Shell AG), followed. Some of them lost interest in this speciaUty market sector. Table 13 indicates the BMI resins available at the end of 1992. No reference is made to prepreg systems available from various sources. A complete Hst of available products and information on any particular material should be obtained from the suppHers.
