Stabilizers properties

Within this category, the greases are divided into those based on simple soaps and those based on complex soaps. The latter generally have better high temperature and structural stability properties under high mechanical shear they also have higher resistance to water than their simple soap-based counterparts. [Pg.280]

Aluminum complex greases, obtained by the reaction of aluminum isopropylate with a mixture of benzoic acid and fatty acids. These greases have a remarkable resistance to water, very good adhesion to metallic surfaces, good mechanical stability properties and resistance to temperature. They are less common than the first two types. [Pg.281]

To obtain the unconditional stability of the midpoint method in local coordinates, one would have to consider the decoupling transformation from cartesian to local coordinates for the discrete variables etc. But this transformation, which for the continuous variables is not constant, necessarily is in error which depends on k, not e. The stability properties of the discrete dynamical systems obtained by the midpoint discretization in the different sets of coordinatc.s may therefore be significantly different when it 3> e [3]. [Pg.291]

The surface active properties of aHphatic amine oxides were discovered ia the 1930s and the wetting, detergent, emulsion, and foam stabilizing properties were published shortiy thereafter (42). However, the use of amine oxides was not significant until Procter and Gamble started usiag them ia household products around 1960 (43—46). [Pg.192]

For rosins and rosin esters, the produets having high aeid numbers are the most susceptible to oxidation and have inferior viscosity stability and colour stability in adhesive formulations. Thus, when stability properties are essential in adhesives, rosin esters rather than high aeid number rosins are used. However, the high acid number resins are polar and display better adhesion to polar elastomers and polymeric surfaces. [Pg.616]

The isobutyl sulfonate was examined as a replacement for the isopropyl sulfonate, which had undesirable stability properties. Cleavage occurs with 2 eq. of Bu4N I and proceeds much more readily than cleavage of the isopropyl sulfonate. ... [Pg.452]

The stability properties of the Pd-V system is well studied both experimentally as well as by theoretical methods. Being a well studied alloy, we have results available for comparison so that the reliability of our methodology can be demonstrated. [Pg.27]

The effect of local activation accounts for such features of PCSs as catalytic and stabilizing properties, autocatalysis, specific properties of thermal degradation, structural modification, and a number of other phenomena typical of polymers with a system of conjugated bonds. [Pg.37]

PEGs are often reacted with fatty acids to make detergents that have thickening and foam-stabilizing properties. When chemically combined with fatty acids from coconut oil, they make detergents such as PEG-5 cocamide, which is used in shampoos as a surfactant, emulsifier, and foam stabilizer. [Pg.136]

In accordance with the results reported previously (ref. 8), the different stability properties of the isomers and the model calculations using numeric s and p, parameters we can use the approximation of ki, k3 > > IC4, as well. Thus, Equations (9) and (10) can be rewritten in simplier forms... [Pg.268]

The relation B > 0.5 tA is ensured by the stability property of this scheme. [Pg.568]

The purpose of this section is to enable the reader to identify the potential stability properties of a chemical substance by simply analysing its structural formula. This will be made possible by listing the structural properties of unstable molecules. The reader will see the need to identify two types of structural properties those that bear the hallmarks of an unstable property and those whose presence can increase or alternatively reduce the risk of violent decomposition. Since the latter are the only ones in the molecule, they do not represent any danger for it in terms of stability. But when performing qualitative analysis, one also has to take into account the conditions under which the substance is handled. In addition to the structural properties, the analyst will have to carry out a study on the external risk factors. [Pg.96]

Annealing. This softens work-hardened and heat-treated alloys, relieves stress, and stabilizes properties and dimensions. [Pg.201]

This equation, of course, contains information regarding stability, and as it is written, implies that one may match properties on the LHS with the point (-1,0) on the complex plane. The form in (7-2a) also imphes that in the process of analyzing the closed-loop stability property, the calculation procedures (or computer programs) only require the open-loop transfer functions. For complex problems, this fact eliminates unnecessary algebra. We just state the Nyquist stability criterion here.1... [Pg.155]

Strapped tetramines show conformationally rigid coordination environments that can lead to novel stability properties. The coordination properties of bowl-shaped cavities or adamanzanes such as the ligand l,5,9,13-tetraazabicyclo-[7.7.3]nonadecane (95) were investigated.745 The... [Pg.1213]

The observation that the quaternary ammonium monomer content of MDTHD.-DMAEMA and DMAEMA CH3C1 DMAEMA copolymers had little effect on their silica fines stabilization properties of prompted an investigation of nonionic polymers as mineral fines stabilizers (17,18). A series of N-vinylpyrrolidinone (NVP) copolymers with DMAEMA have been studied. Results are summarized in Table VII. [Pg.220]

Monomer reactivity ratios and thus comonomer sequence distributions in copolymers can vary with copolymerization reaction conditions. The comonomer distribution could affect the geometry of the adsorbed polymer - mineral complex and the fines stabilization properties. [Pg.222]

Generally diaryl cyclopropenones are thermolyzed at lower temperatures than dialkyl cyclopropenones, e.g. diphenyl cyclopropenone 150 °C, di-n-propyl cyclopropenone 190 °C, due to the better stabilizing properties of alkyl substituents. [Pg.63]
