43) also sulfonated
a t-butyl-styrene-isoprene copolymer.
Large-scale preparative titrations were performed in essentially the same manner as described above with the following exceptions: 1) the concentration of sulfonated
PS-PIB-PS was approximately 0.
For the sulfonated
ionomer, the functionalization of PS with between 5 and 10 mol% sulfonate groups increases the melt viscosity of the PS by about three orders of magnitude, as has been observed before (39).
The NMR data of the homopolymer and sulfonated
copolymers are given below.
It can be expected that this sulfonated
carbon material may able to catalyze the selective hydrolysis of the other di-O-isopropylidene sugars.
In FTIR spectrum of sulfonated
poly(arylene ether benzimidazole) copolymer shown in Figure 5, peaks at 3000-3500 [cm.
Patent 5,637,758, Liquid Detergent Compositions Comprising Salts of Alpha Sulfonated
Fatty Acid Fsters and Anionic Surfactants, Jun.
Various salts are prepared from sulfonated
product carefully at a temperature between 0-10[degrees]C by using appropriate basic solutions as shown in the table.
On the demand side, exporters and strategic planners focusing on acetals, hemiacetals, and their halogenated, sulfonated
, nitrated, or nitrosated derivatives in the United States face a number of questions.
Similarly we have also reported the adsorption studies of Cr3+ with different copolymers of sulfonated
26 mmol/g exhibited comparable proton conductivity to that of the perfluorinated ionomer membrane (Nafion[R] 117) under a wide range of conditions (80-120[degrees]C and 20-93% relative humidity) , The poly(ether sulfone)s containing sulfonated
binaphthyl units also had low water uptake, swelling ratio, and water insolubility even with high IEC value compared to a typical sulfonated
polyfether ether sulfone) , Owing to the high IEC value 3.
Colonial Chemical's sulfonated
surfactant, Suga Nate 100, has received the U.
