AES resin

In general, although EPDM rubber is more expensive than polybutadiene rubber, the amount of EPDM rubber used in AES resin is as low as about 60% of the content of polybutadiene used in ABS resin, and therefore, the price of AES resin as a whole may be somewhat competitive. In addition, since the moldability of AES resin is somewhat better than that of ABS resin, AES resin can be regarded as having high possibility of use if the environmental problem as mentioned above can be solved.

The representative resin includes ASA resin using acryl rubber instead of butadiene rubber and AES resin using EPDM rubber. Those resins are for use outdoors without postprocessing such as painting and metal plating and have been reported to have comparable properties, moldability, and weatherability. 

Polybutadiene has a major application as an impact modifier for polystyrene and acrylonitrile-butadiene-styrene (AES) resin, with about 25% of the total volume of ER going into these applications. Typically, about 7% polybutadiene... 

Sodium trimetaphosphate was used as an eluting agent for the removal of heavy metals such as Pb, Cd, Co, Cu, Fe, Ni, Zn and Cr from aqueous solutions. Distribution coefficients of these elements have been determined regarding five different concentrations of sodium trimeta phosphate (3T0 M 5T0 M 0.01 M 0.05 M 0.1 M) on this resin. By considering these distribution coefficients, the separation of heavy metals has been performed using a concentration gradient of 3T0 - 5T0 M sodium trimetaphosphate. Qualitative and quantitative determinations were realized by ICP-AES.

The benefits imparted by preconcentration to improved sensitivity are illustrated in the example of lead preconcentration on Chelex 100 resin [871,872], followed by analysis by ICP-AES. Without preconcentration the best detection bmit achievable is 60 ng/1, via direct nebubsation. When the Chelex 100 preconcentration step is included, the detection limit improves to 0.6 ng/1, i.e., 100 times better, which is a very important improvement achieved in the analysis of seawaters. Examinaton of Table 5.12 reveals that the following metals can be determined with detection limits in the 1 -10 ng/1 range beryllium (0.6 ng/1),...

Many properties of composites filled with nonreinforcing fillers, such as coefficient of expansion, heat deflection, and specific heat, may be estimated from the rule of mixtures. Thus the coefficient of expansion of the composite, ae, is related to the sum of the coefficients of expansion of the continuous phase or resin matrix m and the discontinuous phase or filler/times their fractional volumes V and (1 — V)% respectively, as follows ... 

On the other hand, high impact poly(styrene) (HIPS), ABS, acrylonitrile-ethylene-propylene-based rubber/styrene copolymer resin (AES), acrylonitrile/acryl-based rubber/styrene copolymer resin (AAS) show excellent impact strengths, but these resins are inferior in chemical resistance and abrasion resistance.

Several other microanalytical methods in common use potentially have application on soil and sediments section samples. Laser-ablation inductively coupled plasma mass spectrometery (LA-ICP-MS) has been used on soil thin-sections from a controlled field experiment (21) but required special resins in the preparation. There is presently (May 2006) no reported use of this method on archaeological soil samples. Likewise, for extremely fine-resolution studies (i.e. <10 pm) with low minimum detection limits and despite difficult calibration, secondary ion microscopy (SIMS) has a potential role in examining archaeological soil thin sections. At even higher lateral resolutions ( 100 nm) Auger electron spectroscopy (AES) could also be considered for surface (<5 nm deep) analyses. At present however, the use of these methods in soil systems is limited. SIMS has been focused on biochemical applications (22), whereas AES... 

It is clear that the acoustic emission technique is capable of providing valuable information on the in situ strength of surface treated fibers, especially at very small gauge lengths approaching the critical aspect ratio of the fiber in the composite. The AE method should also be useful in extending the SFC test to opaque matrix resins, through which fiber fracture cannot be observed by the optical microscope.

Pohl and Prusiz [120] used and compared the performance of the chelating resin Metalfix Chelamine and the strong cation exchanger resin Dowex 50W-X4 for the off-line preconcentration of Cd, Co, Cu, Ni, and Zn. The cation exchanger was selected as the best alternative for the analysis of commercial beer samples by ICP-AES. The preconcentration procedure allowed the selected metals to be determined at concentrations in the order of 1 ng ml-1.
