In non aqueous media, the stability of suspensions requires a polymer with an oil soluble stabilizing chain and a head group with strong adsorption affinity onto the adsorbing surface.
20], found that increase of amino groups in polar anchoring part of succinimide dispersant increase the adsorption affinity of dispersant onto the adsorbing surface which plays an important role in the stability of the suspensions.
That means the elongation of the stabilizing chain is a function of EO units and occurs both parallel to and perpendicular to the adsorbing surface and thus depends upon the ratio between distance s of adjacent chains and their thickness.
Gloss retention results for 18 PVC gloss DTM formulations (Table 2) based on adsorbing polymer EXP-1 and non-adsorbing polymer COM-1 are shown in Figure 5 and Table 1.
The weathering data suggests that the film structure resulting from adsorbing binders such as EXP-1 is a major cause of the improved durability.
The term sticking coefficient is used to describe the probability of an impacting molecule sticking, or adsorbing
, on a surface.
Silver impregnated activated carbons, apart from adsorbing
organic contaminants, also control taste, remove odours, extract colour compounds, filter particles and remove chlorine.
The new polymer, however, "instead of adsorbing
bile acids, would adsorb cholesterol directly," says Borje Sellergren of Johannes Gutenberg University in Mainz.
Depending on the size of the openings, they can adsorb molecules readily, slowly, or not at all, thus functioning as molecular sieves -- adsorbing
molecules of certain sizes while rejecting larger ones.
The patent regarding the invention looks like it will issue soon, a test on adsorbing
ammonia and phosphates from animal waste streams is expected to begin at a slightly later date at a pig farm conducted by a University professor, the new products look terrific and Envirolizr(tm ) should be making sales in roads this year.
