Resin tests

Sample a few resin beads and wash several times with ethanol. 

Transfer to a small glass tube and add 2 drops of each of the solutions above. 

The presence of resin-bound free amine is indicated by blue resin beads. 

Put the sample on a microscope slide, add 1 drop of each solution.

Cation exchange experiments were performed with gel and macroporous resins, and with both simulated and authentic plant solutions. Scouting experiments showed that Dowex 50W x 8 was the most effective cation resin tested. Complexing of Fe + with oxalate ion was also necessary to obtain adequate column capacity. Test data are summarized in Table II. 

Since the Amberlyst XN-IOIO/BF3 catalyst produced an alkylate with quality superior to the other resins tested, additional work was performed with this resin/ BF3 catalyst to explore the effects of particle size and temperature, and sensitivity to olefin type. Olefin space velocity was kept at 2.6 grams C4=/gram resin-hour for all the results reported below. 

Among the resins tested, the Amberlyst XN-IOIO/BF3 catalyst system appeared to be the most selective one, producing the best alkylate quality. This catalyst showed much less difference among different butene feedstocks than conventional HF and H2SO4 alkylation catalysts. In addition, its alkylate quality was improved as the temperature was decreased, reaching a plateau at about 0°C at which an alkylate with a R( I clear of... 

Because of the high scattering of experimental results and the great difficulty in reaching the fully cohesive failure of wooden adhesive Joints, a numerical analysis has been made to give a better knowledge of their mechanical behaviour for various parameters (adhesive used. Joint thickness, loading mode, etc...). For the PU resin tested previously in shear, such an analysis has been made on two steps first simulations have been made on bulk adhesive specimen to determine the mechanical behaviour of the resin and the numerical results obtained have been implanted in the FE code CASTEM 2000 [21] for the mTENF bonded specimen loaded by shear.

The ideal resin would have high actinide capacity and give complete recovery of plutonium and americium in a small volume of elutriant. Each of the resins tested has apparent advantages and disadvantages, which can best be compared by referring to Table II and Figures 2 and 3. (Figures 2 and 3 show the percent recovery as a function of column volumes for plutonium and americium, respectively.)...

The kinetics of the DEHPA-TOPO resins tested are slow compared to other conventional anion exchange resins used for uranium sorption, but about 5 to 10 times faster than with an ion-exchange resin containing aminophosphonic groups (DES 467, Dia-Prosin). The rate of uranium adsorption from 6 M phosphoric acid solutions was studied extensively with...

According to the Multiple Comparison Test statistically significant differences are seen for AP between UFI or UFII and UF III there is no statistically significant difference for AP between UF I and UF II. According to the Kruskal-Wallis test there is no statistically significant difference between the values for FIR between the three resins tested.

Agitate the reaction suspension for 18 h at room temperature, and monitor the progress of the cyclization reaction by resin test (e.g. Kaiser, TNBS, etc. see Chapter 3, Protocol 73). 

It is recommended that patch tests are undertaken with the resin the patients actually handle themselves, in addition to those allergens available from commercial sources. If an individual brings their own resin, we test at 1% and 5% and in petrolatum and, if positives are identified, controls will need to be tested. I have not seen any false positives, but Kanerva et al. (1997) showed that phenol-formaldehyde resin tested at 1% and 5% in petrolatum could produce false-positive reactions on occasions. Hermal provides a Resol and Novalak resin at 5% for patch... 

In conclusion, the porosity, hardness, and strength of microwave cured acrylic resins that are processed for less than 5 min exhibited no significant differences in properties when compared with conventionally polymerized resins [60-63]. However, the investigation of color stability of several commercially available heat-cured, quick heat-cured denture and microwave cured denture base resins (tested exclusively under microwave conditions) revealed that the materials demonstrated differences in color stability, but the standard heat-cured materials treated under microwave irradiation exhibited color changes that were negligible [64].

However, rubbers other than "natural" were also briefly tested and could be used wherever natural rubber is not available, although higher in cost. Alternate rubber binder resins tested included ...
