Materials, Oomstarch was Glebe 3005 ftan CPC International, Inc. Acaylonitrile (99+%) was from Aldrich Chemical Odqpany, Inc., and AASOsH was Lubrizol 2404 traa the LJbrizaL Corporation. Both monomers were iised as received. Ceric anmonium nitrate was Fisher Certified A.C.S. Grade. 

MACROMER (10) is a trademark by CPC International of a new family of monomers. Because they are synthesized via anionic chemistry, their molecular weight is controlled by the ratio of monomer to initiator and they also have very narrow molecular weight distributions. The typical polymeric portions of MACROMEHf that have been investigated are polystyrene, polydiene, and blocks of the two (5, lCi). Some of the typical MACROMER functional groups that were examined are shown in Figure 8. These are shown to indicate the wide variety of functional groups that are useful for various polymerization mechanisms (4). 

Dr. French spent 1945 as a research chemist with Corn Products Co., (at present, CPC International) at Argo, Illinois, working on projects of importance in the manufacture and utilization of starch. After one year with the Corn Products Co., he joined the Faculty of the Chemistry Department at the Iowa State University as Assistant Professor of Chemistry. In 1951, he was promoted to Associate Professor of Chemistry, and, in 1955, to Professor of Chemistry. When the Department of Biochemistry and Biophysics was formed at the Iowa State University in 1960, he became Professor of Biochemistry, and three years later, was appointed Chairman of the Department. He held the latter post until 1971, at which time he returned to full-time teaching and research.

The basic patent coverage for use of xylose isomerase to convert glucose to fructose was lost in 1975 as the result of a civil action suit between CPC International and Standard Brands. Tins enabled development of alternate processes. By 1978. the estimated US production volume was 3.5 x 109 lb and consisted mostly ot syrups containing 42% D-fructose sold at a 71 % solids level (Antrim et al.). The introduction of large scale liquid chromatographic purification of the fructose enabled production of a 55% fructose which could be used in soft drinks in place of invert from sucrose. 

Materials. Granular Globe Pearl corn starch (Globe 3005 water content about 10%) was from CPC International. Acrylonitrile (Eastman practical grade) was fractionated at atmospheric pressure through a 15-in. Vigreux column, and a center cut was collected. Ceric ammonium nitrate was Fisher certified ACS grade. PAN homopolymer was Polymeric Acrylonitrile Type A from DuPont. 

Data are available by company for industry capacity of two important sweetener products, HFS-42 and HFS-55 (see Chapter 22) (Table 2.8). The largest firm in both 1987 and 1992 was Archer Daniels Midland, with about one-third of total US HFS industry capacity. When capacities for the next three, Tate and Lyle North America (formerly A.E. Staley Mfg. Co.), Cargill and CPC International are included, the largest four accounted for -85% of the total capacity for manufacturing HFS. In the early 1990s, Archer Daniels Midland produced an estimated half of the US fuel alcohol.

These "polymeric monomers" were studied by Milkovich and coworkers at CPC International and assigned the trademark Macromer. Several kinds of Macromers have been synthesized and offer functionalized macromolecules that potentially can be polymerized by a variety of polymerization mechanisms. Such anionically prepared Macromers can be used to attach controlled size grafts to the backbone of another type of polymer (15). 

Materials. Starch used in experiments was commercial, food-grade starch (CPC International Inc., Englewood Cliffs, NJ) having a moisture content of 13%. Cellulose was purchased commercially as a highly purified, finely powdered product (Cellulay-Cellulose, United States Biochemical Corp., Cleveland, OH) and had a moisture content of 6%.
