Amite

Economic Aspects. The first company to introduce nucleated PET mol ding resins was Ak2o Plastics BV with their Amite range. This business has been taken over by DSM NV as part of a portfoHo exchange between the two companies. Du Pont introduced their Rynite fast crystallising materials in 1978, and other manufacturers followed.

Figure 15.15 Space-filling representation of a complex between lysozyme (green) and the Fab fragment of a monoclonal antilysozyme (blue and yellow). The Fab fragment and the antigen (lysozyme) have been separated in this diagram, and their combining surfaces are viewed end-on. Atoms that ate in contact in the complex are colored red both in Fab and lysozyme, except Gin 121 in lysozyme, which is violet. The diagram illustrates the large size of the interaction surfaces. (After A.G. Amit et al.. Science 233 747-753, 1986 courtesy of R. Poljak.)...

Figure 15.16 Detailed views of the environment of Gin 121 in the lysozyme-antilysozyme complex. Gin 121 in lysozyme is colored green both in the space-filling representation to the left and in the ball and stick model to the right. This side chain of the antigen fits into a hole between CDR3 regions of both the heavy (Tyr 101) and the light (Trp 92) chains as well as CDRl from the light chain (Tyr 32). (After A.G. Amit et al..

The moulding of Amite PETP must be carried out with dried material and because of the free-flowing nature of the melt, restricted nozzles should be used...

In the USA producers included Eastman Kodak (Tenite PTMT), General Electric Corporation of America (Valox), and American Celanese (Celanex). In Europe major producers by the end of the decade were AKZO (Amite PBTP), BASF (Ultradur), Bayer (Pocan) and Ciba-Geigy (Crastin). Other producers included ATO, Hills, Montedison and Dynamit Nobel. With the total Western European market at the end of the decade only about 7000 tonnes other companies at one time involved in the market such as ICI (Deroton) withdrew.
