Rheology mechanisms

Behavior. Diffusion, Brownian motion, electrophoresis, osmosis, rheology, mechanics, and optical and electrical properties are among the general physical properties and phenomena that are primarily important in coUoidal systems (21,24—27). Of course, chemical reactivity and adsorption often play important, if not dominant, roles. Any physical and chemical feature may ultimately govern a specific industrial process and determine final product characteristics. 

This chapter describes the effects of various stearates on the rheological, mechanical, and chemical properties of metal sulfonate-containing EPDM s.

Dharmarajan et al. [1995] have prepared com-patibilized blends of PO/PP/styrene copolymer. Blends of 100-0 parts PP, 0-100 parts SMA, 0-15 parts EP-g-l° amine (0.3 mol % amine), and 0-5 parts PP-2° amine (0.4 wt% amine) were combined in an internal mixer at 220°C. Blends were characterized by FTIR, DMTA, TEM, rheology, mechanical properties, lap shear adhesion, and paint adhesion. Properties were compared for blends containing either of the two amine-functionalized polymers alone.

A very important part of emulsion study is the availability of methodologies to study emulsions. In the past ten years, both dielectric methods (1) and rheological methods (2) have been exploited to study formation mechanisms and the stability of emulsions formed from many different types of oils. Standard techniques, including NMR, chemical analysis techniques, microscopy, interfacial pressure, and interfacial tension, are also being applied to emulsions. These techniques have largely confirmed findings noted in the dielectric and rheological mechanisms. 

The dimensioning of the mold (phase II of the mold design) essentially includes the rheological, mechanical, and thermal mold layout. These aspects of the layout can be further divided into several steps, each with its own special emphasis ... 

It is evident that there is vast scope for research in injectable dental biomaterials, in terms of chemical development, establishment of new and improved clinical treatment techniques and in fundamental understanding of basic rheological mechanisms.
