a polymerization reaction, and the alkali metal hydroxide is added to the mixture for polymerization reaction continuously or in portions to control the pH of the mixture for polymerization reaction within a range of from 7 to 12.5 from the beginning to the end of the polymerization reaction. The...
The dielectric behavior of n-butyl acrylate undergoing a thermally initiated polymerization reaction was analyzed in the 0.1–10 GHz frequency interval by means of time domain reflectometry. The dielectric behavior of the system was modeled by a superposition of two main relaxation processes, related ...
6-Thioguanine, a thioderivative of the nucleic acid base guanine, is a metabolic inhibitor and possesses antitumor activity. In addition, it inhibits the synthesis of nucleotides and is incorporated readily into the nucleic acid during the polymerization reaction by substituting for guanine. The biolog...
Fluorodinitrobenzene, amino acids, and dinitrophenol amino acids must be present to produce polymerization. The proportion of dinitrophenyl amino acid dimer under equal reaction conditions is in the order glycine .mchlt. b-alanine <e-aminocaproic acid .apprx. w-aminoheptanoic acid .apprx. w-...
After polymerization, the reaction mixture can be rapidly and completely deactivated by adding a deactivator. The deactivator can be added to a heterogeneous phase after the polymer has precipitated in a solvent, or can occur during a homogeneous phase, while the polymer is in a melted form. ...

Comments and corrections on “crystallization during polymerization of diphenylsilylene by a chemical transport reaction”Needlelike crystals of a phenylsilicon compound synthesized on crystallization during polymerization in a transport reaction in a temperature gradient, which were thought earlier to be ...
Polymerization of ethene catalyzed by dicyclopentadienylzirconium dichloride/methylaluminoxane was performed in toluene at 50°C under 0.38–8.95 bar ethene. Both Fourier-transform infrared spectroscopy and gel-permeation chromatography showed that the molecular weight is independent of the ethene pressure (...
We defined single-type burst segments by a constant fluorescence signal with a constant protein reaction rate, and transitional-type segments by a constant fluorescence signal but with a change in protein rate. We observed a total of 177 exonucleolysis and 202 polymerization segments out of 36 ...
The evolution of microstructure during the free-radical polymerization of the surfactant cetyltrimethylammonium 4-vinylbenzoate has been measured using small-angle neutron scattering. The polymerization of the micelles was performed online, collecting SANS data continuously during the polymerization. Unlike mi...
