The kinetics of polymerisation reactions in aqueous solution

Aqueous polymerization of methacrylamide initiated by potassiumpersulfate-L-cystein hydrochloride redox system

“…I~I2SO 4 solutions. The apparatus used was a modified form of that of Baxendale [14]. The kinetics of polymerization has been followed as reported elsewhere [15].…”

The potential controlled Fenton reaction at liquid|liquid interfaces as the source of hydroxyl radicals

“…The ferrocene derivative used as a reactant in the Fenton reaction, the (ferrocenylmethyl)trimethylammonium cation (TMFc þ ) with the hexabromomonocarborane anion [7,8,9,10,11,12-Br 6 -1-CB 11 H 6 ] À (CBB), was prepared from the iodide form of TMFc þ and CsCBB by extraction into chloroform and recrystallized from toluene. The tetrabutylammonium cation (TBA þ ) with the CBB À anion was prepared analogously from TBACl and CsCBB and was used as the base electrolyte in the organic phase of 1,2-dichloroethane.…”

“…The Fenton reaction has been known for quite a long time [8] and thoroughly studied from various angles [9][10][11] including electrochemical approaches [12,13]. For the purposes of our study and for subsequent application, the reactants, i.e., the ferrous ion and hydrogen peroxide, must be separated by the liquid interface in order that the reaction be controlled by potential driven transfer of the charged reactant across the interface into the other phase where the Fenton reaction takes place.…”

Particle Formation in Polymer Colloids, III: Prediction of the Number of Particles by a Homogeneous Nucleation Theory

“…(1) they may precipitate out to form more primary particles, or (2) they may be captured by pre-existing particles, in which case no new particles are formed. This is represented schematically in Figure 9.…”

“…These would ultimately grow to some critical size above which they would precipitate out to form primary particles. Oligomeric radicals formed thereafter would enjoy two possible fates: (1) growth to the critical size followed by precipitation as above (homogeneous nucleation) or (2) "capture" by pre-existing particles. As particle formation continued the probability of capture would increase until ultimately all oligomers would be captured and thereafter no new particles would form.…”
