A study was made of the polymerization of acrylamide (AA) in two-phase systems containing water and in concentrated aqueous solutions in presence of ammonia or caustic soda. It was found that polymers prepared by polymerization in these systems, when

The radical polymerization of acrylamide (AA) has been investigated in the presence of various solvents over lithium bromide (LiBr). Addition of salt has been found not to affect the total rate of the polymerization in water. The use of dimethyl sulp

The radical polymerizations of acrylamide and methacrylamide and of acrylic, methacrylic and fluoroacrylic acids have been studied in various solvents. The nature of the solvent affects the overall rate due to changes in kp and Ep. It has been shown

The influence of the solvent on the rate of radical polymerisation and copolymerisation, observed and investigated in the last ten years and caused mainly by a change in the rate of the elementary chain propagation reaction, is discussed. The publish

A study was made of radical polymerization of acrylamide in dimethylsulphoxide in the presence of various inorganic salts. It was established that the addition of lithium chloride, or calcium chloride markedly changes reaction parameters, but zinc ch

The homogeneous radical copolymerization of acrylic with fluoro-acrylic acid was studied at 50°C in water and DMSO as solvents. The compositions found in water were used to calculate the reactivity ratios, i.e. r 1 = 0·37 ± 0·06, r 2 = 1·58 ± 0

T~E polymerization of acrylamide has previously been studied mainly in solution in water [1-12], in which the monomer and polymer are readily soluble, and also in the solid state under the influence of high energy radiation [13]. Some isolated experi
