The blending chart in Fig. 1 in Chapter 5 shows an exponential dependence of solution viscosity on concentration, within the range of maximum measurable concentration (100%). Rheometry permits higher c, than does viscome-try. As a prerequisite to construction of a linear polysaccharide blending chart, the linear range of t sv/ci vs ci should first be established, because it is only then that the viscosity of the blend will be equal to the sum of the viscosities of the components. Each ordinate in Fig. 1 in Chapter 5 is labeled with the maximum ct of the two polysaccharides of interest or its equivalent as 100%.

Finally, the shear modulus, G, and the phase angle, s, measured by the DSR, in fact the ratio G /sin s, should be used for blending new bitumen with recycled asphalt, when the Superpave PG bitumen classification system is used (ARRA 2001). Relevant information can be found in the same manual (ARRA 2001). A procedure to develop blending charts for RA and virgin binders using the Superpave PG classification is described by McDaniel etal. (2001).

Once the <5 and y values of a given blend are determined, the values are positioned in the graphic chart given in Fig. 37 [77]. The blends that fall within the kidney-shaped area yield good solutions with all solvent grade polychloroprene types, except for Neoprene AH, and those which fall outside that area will not dissolve the polychloroprene. The solvent blends which fall within the shadow area, may or may not dissolve the polychloroprene depending on the amount of toluene. 

An illustrative flow chart of the entire procedure of the blending processing is shown in Scheme 1.

Blends of yellowish-green-light emissive carbazole-containing PPV-based copolymer 105 (Apl = 490, 520 nm, AEL = 533 nm) with blue-emissive oxadiazole- poly-/ -phenylene (PPP) copolymer 106 (AEL = 426 nm) allowed to tune the emission of PLEDs (ITO/polymer blend/Al) from AEL = 533 nm to AEL = 451 nm, although the device turn-on voltage was essentially higher for the blends with increased content of 106 [149] (Chart 2.22). 

Later, Yang and coworkers [84] reported similar electrophosphorescent fluorene copolymers 71 and 72, where the hole-transporting carbazole units have been introduced in the polymer backbone (Chart 4.25). Optimizing the polymer structure (comonomer ratio) and the device structure (blending with electron-transporting material PBD 8), the EQE of 4.9% has been achieved.
