Poly(ethylene terephthalate), the predominant commercial polyester, has been sold under trademark names including Dacron (Du Pont), Terylene (ICI), Eortrel (Wellman), Trevira (Hoechst-Celanese), and others (17). Other commercially produced homopolyester textile fiber compositions iaclude p oly (1,4-cyc1 oh exa n e- dim ethyl en e terephthalate) [24936-69-4] (Kodel II, Eastman), poly(butylene terephthalate) [26062-94-2] (PBT) (Trevira, Hoechst-Celanese), and poly(ethylene 4-oxyben2oate) [25248-22-0] (A-Tell, Unitika). Other polyester homopolymer fibers available for specialty uses iaclude polyglycoHde [26124-68-5] polypivalolactone [24937-51-7] and polylactide [26100-51-6],... [Pg.325]

Boric acid/alkaU spinning has been commercialized in Kuraray Co. and Unitika Co. in Japan, and is reportedly under research and development also in the People s RepubHc of China as a process for producing high strength PVA fiber to be used for replacing asbestos (9). [Pg.339]

Although several companies have produced polyarylates, Unitika in Japan and Hoechst-Celanese are the only ones active in the marketplace. Unitika resin is marketed in the United States by Amoco Performance Polymers under the Ardel trademark. The reason for this decline may be the competition of PC, polyester carbonates, and polysulfone resins. Worldwide sales are quite small, probably less than 1000 t/yr. [Pg.269]

One such material is the copolymer first marketed by the Japanese company Unitika in 1974 as U-Polymer and more recently by the Belgian company Solvay as Arylef and Union Carbide as Ardel. (Around 1986 the Union Carbide interest in Ardel, as well as in polysulphones, was taken over by Amoco.) Similar polyarylates have since been marketed by Hooker (Durel), Bayer (APE) and DuPont (Arylon). This is a copolyester of terephthalic acid, isophthalic acid and bis-phenol A in the ratio 1 1 2 Figure 25.23). [Pg.731]

The material was marketed as a fibre in 1968 jointly by the Japanese companies Unitika and Mitsubishi as A-Tell. The polymer is about 41% crystalline, and has a specific gravity of 1.34, a of 223°C and a Eg of 65°C. The fibres are somewhat silk-like in character. [Pg.732]
