Unfortunately for PPO its price is too great to justify more them very restricted application and this led to the introduction of the related tmd cheaper Noryl materials in 1966 by the General Electric Corporation. These will be discussed in the next section. In recent years the only sources of unmodified PPO have been the USSR (Aryloxa) and Poland (Biapen). 

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.

While the experiments of Pockels and Rayleigh generated some activity on the properties of thin films, the area was essentially dormant until the work of Irving Langmuir (1881-1957 Nobel Prize, 1932, for surface chemistry) at the General Electric Corporate Research Laboratories in Schenectady, New York. Langmuir developed a number of new techniques... 

Cubic boron nitride is commonly called c-BN in literature, but also z-BN (zinc blende) or /1-BN [13] can be found. Wentorf [18] named c-BN Borazon , which has become the trade name for the products of the General Electric Corporation. Russian companies call abrasive powders of c-BN Elbor or... 

Track-etch membranes were developed by the General Electric Corporation Schenectady Laboratory [3], The two-step preparation process is illustrated in Figure 3.4. First, a thin polymer film is irradiated with fission particles from a nuclear reactor or other radiation source. The massive particles pass through the film, breaking polymer chains and leaving behind a sensitized track of damaged polymer molecules. These tracks are much more susceptible to chemical attack than the base polymer material. So when the film is passed through a solution...

The aromatic diamines and dianhydrides used in the preparation of the polyamic acid resins and the diamic acid additives are listed in Figure 1. The 2,2-bis(3,4-dicarboxyphenyl)hexafluoropropane dianhydride (6FDA), 4,4 -oxydianiline (4,4 -ODA), and 3,3 -diaminodiphenylsulfone (3,3 -DDS02) were obtained from commercial sources. The remaining monomers were obtained as experimental materials as follows (1) 4,4 -bis(3,4-dicarboxyphenoxy) diphenylsulfide dianhydride (BDSDA) from General Electric Corporate R D Center (2) 4,4 -oxydiphthalic anhydride (ODPA) from Occidental Chemical Corporation (3) 2,2-bis[4(4-aminophenoxy)phenyl]hexafluoropropane (4-BDAF) from Ethyl Corporation and (4) 2,2-bis[4(3-aminophenoxy)phenyl]hexafluoropropane (3-BDAF) and 3,3 -oxydianiline (3,3 -ODA) from Mitsui Toatsu, Inc.
