Kinetics and mechanism of radical polymerization of weak unsaturated acids in aqueous solutions

Solvent Influence on Propagation Kinetics in Radical Polymerizations Studied by Pulsed Laser Initiated Polymerizations

“…Until recently this was not reflected by the knowledge on polymerization kinetics of these monomers in aqueous phase. Early investigations [89][90][91] showed that variations in monomer concentration or pH may induce significant variations in the rate of polymerizations, but reliable rate coefficients were not available. Within the last decade, the PLP-SEC technique was also applied to polymerizations of water-soluble monomers.…”

Kinetics and reaction mechanism of template polymerization investigated by conductimetric measurements. Part 3. Radical polymerization of acrylic acid in the presence of poly(N-vinylpyrrolidone)

“…These parameters were in quantitative agreement with those obtained from the usual dilatometric technique and those reported in literature. 11,12 Template polymerization of acrylic acid onto poly (N-vinylpyrrolidone) To study the in¯uence of a preformed polymer on kinetic parameters and on the polymerization mechanism, acrylic acid was polymerized in the presence of poly(N-vinylpyrrolidone) (M w = 24 000), in aqueous solution and using potassium peroxodisulphate as radical initiator. Both dilatometry and conductimetry measurements were performed as described for blank polymerizations.…”

“…7 Concerning reaction order, consistent results are obtained from the two techniques and in accordance with the theoretically expected value of unity for a radical polymerization of an acrylic monomer. 12 The activation energy was derived from dilatometric and conductimetric measurements carried out at …”

Effects of Ionization on Tacticity and Propagation Kinetics in Methacrylic Acid Polymerization

“…Some of the most effective (and elegant) strategies, such as stereoregular templating (2)(3)(4), are impractical and could not be readily applied to grams scale polymer synthesis. The strategy that is best able to balance the competing demands of effectiveness and practicality is monomer modification to incorporate bulky (5)(6)(7)(8), chiral (9,10) and ionic auxiliaries (11)(12)(13)(14)(15)(16)(17)(18)(19)(20).…”
