Naito and Kanemitsu (1996) investigated the relationship between the prefactor mobilities, zero-field mobilities, and the glass transition temperatures of OX doped polyarylate (PA), PC, poly(methyl methacrylate) (PMMA), PS, poly(vinyl chloride) (PVC), polyethylene terephthalate) (PET), and poly(vinyl butyral) (PVB), DEH doped PC, 5(p-diethylaminophenyl)-l-phenyl-3-(/ -diethylaminostyryl)-2-pyrazoline (DEASP) doped PS, and DEASP doped PC. OX, DEH, and DEASP are highly polar molecules with similar dipole moments. By modifying the polymer, the glass transition temperature can be varied over... 

Methane and carbon tetrachloride, CCl4, have zero dipole moments. We certainly would expect the individual bonds—of carbon tetrachloride at least—to be nolar because of the very symmetrical tetrahedral arrangement, however, they exactly cancel each other out (Fig. 1.14). In methyl chloride, H CI, the polarity... 

Like alkanes, alkenes are at most only weakly polar. Since the loosely held TT electrons of the double bond are easily pulled or pushed, dipole moments are larger than for alkanes. They are still small, however compare the dipole moments shown for propylene and 1-butene, for example, with the moment of 1.83 d for methyl chloride. The bond joining the alkyl group to the doubly-bonded carbon has a small polarity, which is believed to be in the direction shown, that is, with the alkyl group releasing electrons to the doubly-bonded carbon. Since this polarity is not canceled by a corresponding polarity in the opposite direction, it gives a net dipole moment to the molecule. 

Rainwater and his co-workers have extended their work on heteronuclear hard dumbbells to the treatment of dipolar systems [267]. They have used a generalized van der Waals theory similar to that used for quadrupolar molecules [152,266] to calculate the phase diagram and have compared their results with experiment for methyl chloride. The theory correctly predicts the effect of the dipole moment on the stable crystal structure.
