The asphaltenes were dissolved in toluene and then partially precipitated at specified ratios of heptane/toluene to generate sets of light (soluble) and heavy (insoluble) cuts. The molecular weight and density were measured for each cut. The asphaltenes were found to include both associating and ...
Twenty-three wt % aqueous tackifier dispersion based on glycerol ester abietic acid (Tg = 64°C, Mw = 940) was added to emulsion polymer 50/32/15/3 poly(2-... SD Tobing,A Klein - 《Journal of Applied Polymer Science》 被引量: 119发表: 2000年 Development of solvent-free acrylic pre...
The results showed that R177A and D215A are inactive while H214A exhibit an 11-fold and 27-fold decrease in activity and catalytic efficiency compared to those of the WT. Additionally, slight variations were observed regarding the Kms of the peptide (Fig. 3c and Supplementary Table 1). A ...
(Mn) of the nonvolatile oligomers was calculated by the following equation5 using the limiting viscosity number measured at 30°C in toluene: [1]]=3.71 X 10- 4 P 0 ·75 , where [tJJ is the limiting viscosity number (Lg- 1) and Pis the number average degree of polymerization ...

average molecular weights, Mv of the samples in Table I and their fractions in Tables II, III, and IV were evaluated from their intrinsic viscosities using the following Mark-Houwink- Sakurada equation for poly(a-methylstyrene) having a narrow molecular weight distribution in toluene at 25°C....
Firstly, 50.5 mg of toluene, 50.3 mg of dimethyl-naphthalene, and 50.4 mg of pyrene were added in sequence into 25 mL of CCl4 with C2Cl6 as internal standard. Then, the solution was diluted for four times with CCl4 to obtain a series of solution with different solute ...
In a process for preparing a selectivated catalyst composition useful in the disproportionation of toluene, a catalyst comprising an acidic molecular sieve is contacted w
