Degree of incompatibility

Generally, a graft copolymer should offer a clear advantage over the physical blend when a high degree of incompatibility exists between the component parts. It is... 

Note 2 The term degree of incompatibility is sometimes used instead of degree of compatibility. Such use is discouraged as incompatibility is related to the weakness of interfacial bonding. 

The data we found also show that the greater the ATg, the greater the degree of incompatibility. No research has been done to discover the minimum value of ATg for which incompatibility still occurs, but studies are in progress. On the basis of this ascertained incompatibility... 

Abundances of nonrefractory incompatible lithophile elements (potassium, rubidium, caesium, etc.) or partly siderophile/chalcophile elements (tungsten, antimony, tin, etc.) are calculated from correlations with RLE of similar compatibility. This approach was first used by Wanke et al. (1973) to estimate abundances of volatile and siderophile elements such as potassium or tungsten in the moon. The potassium abundance was used to calculate the depletion of volatile elements in the bulk moon, whereas the conditions of core formation and the size of the lunar core may be estimated from the tungsten abundance, as described by Rammensee and Wanke (1977). This powerful method has been subsequently applied to Earth, Mars, Vesta, and the parent body of HED meteorites. The procedure is, however, only applicable if an incompatible refractory element and a volatile or siderophile element have the same degree of incompatibility, i.e., do not fractionate from each other during igneous processes. In other words, a good correlation of the two elements over a wide... 

In s unimar, the PP/LLDPE blends are Immiscible and the degree of incompatibility increases with molecular weight of the homopolymers. An increase of molecular weight also shifts the appearance of the apparent yield stress to higher frequencies accessible In standard test equipment. The yield stress seems to be associated with flow and deformability of co-contlnuous blend structure. The... 

During partial melting trace element behavior is governed by the preference of a particular element for its host (a mineral phase) or the melt phase. Elements which tend to become part of the melt are known as incompatible elements, and those which prefer to remain in the mineral phase are known as compatible elements. In detail this is governed by relationships between the particular element and the structure of the relevant mineral phase. The degree of incompatibility of a specific element in a particular mineral phase is expressed as the mineral-melt partition coefficient. Incompatible elements have mineral-melt partition coefficients <1.0 and highly incompatible elements have partition coefficients compatible elements have partition coefficients of > 1.0. 

Adhesives. The development of tack is associated with a slight degree of incompatibility which is evidenced only (I) by a loss of gloss. The formation of two phases may in itself be an explanation of the adhesion, one phase being very stickly while the other phase maintains strength. 

For a green sand monosystem, regeneration ratios of 98 % may be achieved. Systems with a high degree of incompatible cores, may achieve a regeneration ratio of 90 - 94 %. 

Mixtures of telomers of molecular weights as low as 1000 g/mol have critical temperatures above the decomposition points of the polymers, illustrating the high degree of incompatibility of this particular pair.
