The fits are to stretched exponentials Z oexp(—aM ) in matrix molecular weight M. The Table gives the best-fit parameters, the percent root-mean-squaxe fractional fit error %RMS, the system, and the reference. Square brackets [ ] denote paxameters that were fixed rather than floated. Abbreviations as per previous Tables, and DBP-dibutylphthalate. 

NFS spectra of the molecular glass former ferrocene/dibutylphthalate (FC/DBP) recorded at 170 and 202 K are shown in Fig. 9.12a [31]. It is clear that the pattern of the dynamical beats changes drastically within this relatively narrow temperature range. The analysis of these and other NFS spectra between 100 and 200 K provides/factors, the temperature dependence of which is shown in Fig. 9.12b [31]. Up to about 150 K,/(T) follows the high-temperature approximation of the Debye model (straight line within the log scale in Fig. 9.12b), yielding a Debye tempera-ture 6x) = 41 K. For higher temperatures, a square-root term / v/(r, - T)/T,... 

Table 2.7 lists techniques used to characterise carbon-blacks. Analysis of CB in rubber vulcanisates requires recovery of CB by digestion of the matrix followed by filtration, or by nonoxidative pyrolysis. Dispersion of CB within rubber products is usually assessed by the Cabot dispersion test, or by means of TEM. Kruse [46] has reviewed rubber microscopy, including the determination of the microstructure of CB in rubber compounds and vulcanisates and their qualitative and quantitative determination. Analysis of free CB features measurements of (i) particulate and aggregate size (SEM, TEM, XRD, AFM, STM) (ii) total surface area according to the BET method (ISO 4652), iodine adsorption (ISO 1304) or cetyltrimethylammonium bromide (CTAB) adsorption (ASTM D 3765) and (iii) external surface area, according to the dibutylphthalate (DBP) test (ASTM D 2414). TGA is an excellent technique for the quantification of CB in rubbers. However, it is very limited in being able to distinguish the different types of...

Apparently, the formation of the microporous structure within the PVdF—HFP copolymer was of critical importance to the success of Bellcore technology, and the ion conductivity was proportional to the uptake of the liquid electrolyte. To achieve the desired porosity of PVdF film, Bellcore researchers prepared the initial polymer blend of PVdF with a plasticizer dibutylphthalate (DBP), which was then extracted by low boiling solvents after film formation. Thus, a pore-memory would be left by the voids that were previously occupied by DBP. However, due to the incomplete dissolution of such high-melting DBP during the extraction process, the pore-memory could never be restored at 100% efficiency. Beside the total volume of pores thus created by the plasticizer.

Compatibility of PVC with plasticizer (PI) also strongly influences the rheological and processing properties of plastisols 48>. The effects of the diverse plasticizers on PVC varies since some plasticizers (even well compatible with polymer), e.g. dibutylphthalate (DBP), may readily escape from the obtained materials and articles 17,23,43. Plasticizers which are poorly compatible with PVC (the so-called secondary PI ) may be used for the purpose-oriented change of viscosity properties of a system (fluidity increase) and saving the base PI component.

Dioctyl phthalate (DOP or DHEP, di-2-ethylhexyl phthalate) is the most broadly used phthalate plasticizer counting for more than 50% of world plasticizer consumption. Other broadly used phthalate plasticizers are diisononyl phthalate (DINP) and diisodecyl phthalate (DIDP), whereas butylbenzyl phthalate (BBP) and diisotridecyl phthalate are regarded as specialty phthalates. Dibutylphthalate (DBP) is mainly used as a plasticizer in coating applications to flexibilize nitrocellulose resins. 

Typical plasticisers include dimethyl phthalate (DMP), diethyl phthalate (DEP), dibutylphthalate (DBP), di 2 ethylhexyl phthalate (often known as DOP). Other plasticisers include epoxy-based materials, e.g. octyl epoxy stearate, and, more recently, polyurethane-based materials. 

Phthalates are the most frequently used esters. Dibutylphthalate (DBP) tends to give soft compounds with tack dioctylphthalate (DOP) is less volatile and tends to produce harder compounds because of its higher molecular weight. Polymeric esters such as polypropylene adipate (PPA) are used when low volatility is required along with good heat resistance. 

Polymers are also used to form compounds that, when added to building materials, modify their properties. For example dibutylphthalate (DBP) is often used as a plasticizer to improve the flexibility of a plastic formulation.
