ABSTRACT
The application of water soluble polymers and composites is continuously expanding. Investigations are encouraged into the synthesis of water soluble polymers by novel and traditional methods aimed at producing polymers of a predetermined chemical composition, structure, molecular weight and propagation of chemical chains in macromolecules. Kinetic studies of the polymerization of N,N-Dimethyl-N,N-Diallyl Ammonium Chloride in water were carried out calorimetrically. The Tian-Calvet microcalorimeter used under isothermal conditions, measures the heat of chemical reaction with a sensitivity of 0,00072 Wt/mm and measurement error of 3,5%. The kinetic curves are S-like in shape which is typical of gel-effect reactions. The length of the linear segment of the kinetic curves and the corresponding initial polymerization rate values, estimated from the calorimetric data are in satisfactory agreement with the parameters obtained from the dilatometric measurements. Analysis of the kinetic curves shows that after a weak initial segment, the anti-acceleration occurs indicated by a sharp rise in the reduced polymerization rate.
