Supports physical characteristics

SynChropak size exclusion supports are composed of spherical uniformly porous silica that has been derivatized with a suitable layer. SynChropak GPC supports are available in six pore diameters ranging from 50 to 4000 A and particle diameters from 5 to 10 /zm. SynChropak CATSEC supports are available in four pore diameters. Table 10.1 details the physical characteristics of the product lines. 

All consumer films and professional stock continue to be offered on cellulose triacetate. All its X-ray and micro photographic film is supported on PET. Only Advantix is on PEN. The primary issue is the cost of PEN, which may be why it has not been adopted widely in packaging. Its transport characteristics for bottles is excellent because of its physical characteristics. Its cost is high but a premium price in a premium product is more acceptable than it would be in Kodak s mainstream product range. 

In this section of our review, recent developments in the synthesis of organosiloxane containing multiphase copolymers and networks will be discussed. Basic structural and physical characteristics of the copolymers (e.g. spectroscopic, thermal, molecular weight, etc.), supporting the formation of the multiphase structures will be given. Mechanical and morphological characteristics of representative systems will be discussed in Chapt. 4. 

In many cases drying operations are critical to the production of successful commercial catalysts. Close control of the drying process is necessary to achieve the proper distribution of the catalyst precursor within the pore structure of the support. Drying also influences the physical characteristics of the finished catalyst and the ease with which subsequent pelleting or extrusion processes may be carried out. 

Thus both physical characteristics and environmental findings support the long-range transport of PCCD/PCDFs and PCBs. There are differences, however, both between and within the groups regarding ability to undergo LRTAP. 

Add to the list from step 2 all assumptions you take for granted about the current solution. Include factual data, physical characteristics, supporting... 

Ivanchev et al. compared, under the same ethylene polymerization conditions, the performances of some supported systems with those of traditional ones. The authors not only found that the activity of supported systems is determined by the chemical-physical characteristics of the carrier, which influence the number and the propagation constant of the active centres, but also, in agreement with other authors that changes take place, in the elementary polymerization processes, such as to modify the polymer molecular structure. Indeed, as one can observe (Table 6), it is... 

Note again that the critical exponents do not depend on the physical characteristics of any material. Therefore, all data pertaining to their properties near the critical point should collapse onto a single curve, as is exemplified for fluids by Fig. 7.1.3. Other types of verification and tests are quoted in the literature, lending strong support to the basic soundness of the approach. In other words, we may assume the appropriateness of using relations such as (7.2.6), (7.2.7), (7.2.11) in interpreting the properties of materials near their critical points.
