Hydrocarbons have, for the most part, replaced CFCs as propellants. Most personal products such as hair sprays, deodorants, and antiperspirants, as well as household aerosols, are formulated using hydrocarbons or some form of hydro-carbon—halocarbon blend. Blends provide customized vapor pressures and, if halocarbons are utilized, a decrease in flammabiUty. Some blends form azeotropes which have a constant vapor pressure and do not fractionate as the contents of the container are used. 

Nitrile rubber/phenolic resin blends. Blends of equal parts by weight of a nitrile rubber and a phenolic resin in methyl ethyl ketone (at a 20-30 wt% total solids content) is suitable for many adhesive purposes. The more phenolic resin in the formulation, the greater the bond strength and brittleness of the NBR adhesive [67]. Table 10 shows the effect of phenolic resin on nitrile rubber properties. On the other hand, the higher the acrylonitrile content in the rubber.

Another study looked at the miscibihty of E-plastomer-polyisobutylene blends. Blends were prepared from linear E-plastomers and a polyisobutylenes in the entire composition range. Flory-Huggins interaction parameters were determined from DMTA and DSC measurements. The usual technique had to be modified in the case of DSC data, since the Tg of E-plastomers cannot be detected by this technique. The two methods yielded identical results and indicated good interaction of the components, which was supported also by a SEM study and the mechanical properties of the blends.

Experimental conditions were 727, 756, and 794 K isothermal reactor temperature 827-, 1220-, and 2619-kPa hydrogen pressure 138- and 345-kPa hydrocarbon pressure and 1 to 26 liquid hourly space velocity. (See Section II for definition.) Charge stocks consisted of three C6 component blends (blends included 53/19/23/5, 25/75/0/0, and 0/0/50/50 wt. % hexane/methylcyclopentane/cyclohexane/benzene), C6 to C7 component naphthas (322-366 K TBP Kirkuk, Mid-Continent, and Nigerian), a C6 to C8 component naphtha (322-416 K TBP Mid-Continent), and C6 to C12 component naphthas (322-461 K TBP Arab Light, Mid-Continent, and... 

HPL/PMMA Blends. Blend Structure. All blends of HPL and PMMA revealed a two-phase (immiscible) morphology regardless of solvent, weight fraction, molecular weight (of PMMA), or method of preparation (9). Extruded HPL/PMMA blends exhibited a less obvious two-phase morphology (9), and this was attributed to differences in the rate of vitrification (9). 

Blending. Blending time for WUA must be carefully controlled, or can be used as an experimental variable. Note, however, that excessive blending may lead to emulsification, which would most likely lead to a poorer separation between the pellet and the supernatant. The amount of solution added must be carefully measured, as must the amount of supernatant after centrifugation.

Polymer Blends. Blending of polymers with each other accounts for approximately 40 percent of the present plastics market, and the practice is growing continually, because it permits the development of improved properties without the cost of inventing new polymers. When polymers are fairly miscible, as in the polyethylenes, and in polyphenylene ether plus polystyrene, blending can be used to produce intermediate properties and balance of properties. Most polymer blends...
