P—O—Ethyl group has one or two weak bands in the 1250 cm" region, but they are not sufficiently strong or sufficiently characteristic to be of value. 

Applications. Among the P—O- and P—N-substituted polymers, the fluoroalkoxy- and aryloxy-substituted polymers have so far shown the greatest commercial promise (14—16). Both poly[bis(2,2,2-trifluoroethoxy)phosphazene] [27290-40-0] and poly(diphenoxyphosphazene) [28212-48-8] are microcrystalline, thermoplastic polymers. However, when the substituent symmetry is dismpted with a randomly placed second substituent of different length, the polymers become amorphous and serve as good elastomers. Following initial development of the fluorophosphazene elastomers by the Firestone Tire and Rubber Co., both the fluoroalkoxy (EYPEL-F) and aryloxy (EYPEL-A) elastomers were manufactured by the Ethyl Corp. in the United States from the mid-1980s until 1993 (see ELASTOLffiRS,SYNTHETic-PHOSPHAZENEs). 

Plasticisers are comparatively uncommon but plasticised grades are supplied by some manufacturers. Plasticisers lower the melting point and improve toughness and flexibility, particularly at low temperatures. An example of a plasticiser used commercially in Santicizer 8, a blend of o- and p-toluene ethyl sulphonamide (Figure 18.18). 

Determination of Rotatory Power. —The 1 otatory p o < 1 of ethyl tartiate, which is an optically active substance, is determined by means of a polarimetcr. One of these insti U-ments known as Laurent s polarimeter is shown in l- igs. 71 and 72.

Miscellaneous spectral studies include e.s.r. spectra of chloro-phosphines (2)6 and vibrational spectra of various phosphines.6-8 N.m.r. studies include those of borane complexes of aryldichlorophosphines,9 and studies of the conformation of dichloro-(isopropyl)phosphine (3)10 and dichloro(ethyl)phosphine (4).10 These phosphines have the preferred conformations shown. Conformation has also been the theme of electron-diffraction work on the anhydride (5), which appears to have a staggered conformation.11 The electronic implications of a relatively short P—O bond and wide POP angle have been discussed.11...

Hexanone has also been shown to potentiate the neurotoxic effects of some compounds. In hens, dermal or inhalation exposure to 2-hexanone in combination with dermal application of the pesticide O-ethyl-O-4-nitrophenyl phenylphosphonothioate (EPN) has resulted in earlier onset and far more severe clinical and histological manifestations of neurotoxic effects than with either chemical exposure alone (Abou-Donia et al. 1985a, 1985b). The authors speculated that this potentiation effect may have been due to induction of hepatic microsomal cytochrome P-450 by EPN, leading to increased metabolism of 2-hexanone to its neurotoxic metabolite, 2,5-hexanedione. An alternate explanation is that local trauma to the nervous tissue produced by 2-hexanone and EPN might increase vascular permeability and thus increase the entry of these compounds and their metabolites from circulation.
