Presentation Outline • Celanese AG at a glance • Brief history • 5 major segments, or branches of the company • Overview of Celanese Chemicals • Overview of Celanese Acetate (concentration on acetate) • Overview of Ticona (concentration on Topas®) • Overview of Nutrinova (concentration on Sunett®) • Overview of Trespaphan • Conclusions and/or Questions

3. Celanese AG at a Glance • 30 prod. sites in 11 countries • R&D centers at 6 of these sites • Net sales in 2000, 4.9 billion US Dollars • 21% increase in sales from the previous year • 48% sales in North America • 35% sales in Europe • 13% sales in Asia • 4% sales in South America, Africa, and the South Pacific

4. 1912-Dreyfus brothers, Henri and Camille, produce fireproof celluloid out of cellulose acetate 1913-Cellonit is established, furnishes the paint for German airplanes 1916-British govern. supports Dreyfus brothers and they begin producing acetic acid as well as paint 1917-Camille Dreyfus founds Amcelle in New York 1918-WWI ends and airplane paint isn’t needed. Dreyfus brothers concentrate on acetate fibers, “British Celanese” 1921-British Celanese begins commercial prod. of acetate yarn History of Celanese Camille Dreyfus

5. 1927-Amcelle in US changes to “Celanese Corp. of America”, producing fibers, plastics, and chemicals 1945-1955-Celanese/America begins producing acetaldehyde, formaldehyde, methanol, and acetone 1961-Celanese/America and Hoechst AG set up Ticona. 1963-Ticona begins producing polyacetate Hostaform, a hi-po plastic for technical application 1979-Hoechst AG takes over polyester film business of Celanese in NC 1987-Hoechst AG acquires Celanese Corp. for $2.85 billion 1994-Realignment of the new joint organization, the Hoechst Celanese Corp. 1998-Hoechst announces plan to demerge most of its chemical activity to the new Celanese AG 1999-In July, the demerge takes place, Celanese AG is formed and Hoechst is free to concentrate on life sciences 1999-October, Celanese AG becomes publicly traded stock corp., listed on the NY and Frankfurt stock exchanges

6. 5 Segments of Celanese

7. Manufactures andmarkets chemicals throughout the world World’s #1 or #2 producer in most of their chemicals Over 7,000 employees at 25 major sites 2 main divisions / Acetyl Products & Chemical Intermediates • AcetylProducts • methanol • formaldehyde • polyols • acetaldehyde • acetic acid • vinyl acetate monomer • *These chemicals are all used in adhesives, paints, coatings, and textiles • Intermediates • acrylic acid & acrylates • *Used in superabsorbent polymers(diapers, paints, etc) • butanol & propanol • butylaldehyde • *Organic solvents • carboxylic acids • various amines • *Intermediates for pharmaceutical, agricultural, and chemical products

8. Celanese Acetate is the world’s largest producer of cellulose acetate products Celanese Acetate employs 3,000 people worldwide “Celanese” comes from “cellulose acetate” and “ease of care” Cellulose acetate was produced by Camille Dreyfus during WWI It was used to coat wings of airplanes, making them less flammable Acetate makes up 14% of Celanese’s total sales • Uses of Acetate • Fashion apparel • Linings • Home furnishings • Cigarette filters • Screwdriver handles • Ink pen reservoirs • Host of other industrial end uses

9. Uniqueness of Acetate • MaterialProperties - can selectively absorb low levels of certain organic chemicals and still be easily bonded using heat and/or pressure • ChemicalSolubility - soluble in most solvents • Safetouse - hypoallergenic meaning safe to touch the skin • Environmentallysafe - made from trees • Unlimitedcolors - great affinity for dyes and pigments • Easytoprocess - can be shaped into wide variety of materials • Comfortable – very soft fiber, no static build up, therefore no cling

10. The Process of Acetate

11. Engineer polymers used in making hi-po thermoplastics • Uses • Automotivc • Appliances • Electronics • Industrial • Medical • Info technology • Productlines • Hostoform® • Celcon® • Celanex® • Vandar® • Impet-Hi® • Riteflex® • Vectra® • Fortron® • Celstran® • GUR® • Topas®

12. Topas® • Cyclic-Olefin Copolymers • Amorphous clear copolymers of ethylene and norbornene • Made via metallocene catalysis • Highly transparent • Fracture proof • High moisture barrier • Great for pharmaceuticals, vials, packaging, etc. • Precision optics • Other medical equipment Highly transparent and fracture proof vials for liquid medicines

13. 12 sites around the world Several hundred employees Core business of sweetening and food protection • Sorbic acid • Potassium sorbate • Calcium sorbate • Sunett® • high intensity sweetener • Absolutely safe for humans • Optimum taste • Great stability in processing and storage • Used in 4,000 products worldwide

14. Develops, produces, and markets polypropylene films (OPP films) • OPP films are very strong films manufactured from polypropylene • which are mainly used to package food • Packaging of food-stuffs using transparent films • Packaging of food-stuffs (chocolate bars) using white, opaque films • Packaging of cigarette packs using transparent films • Films for laminates • Films for label manufacture • Films for high-tech application in the electrical engineering industry
