Sažetak

The thermodynamic theory of coagulation kinetics1 was extended in the present paper in order to explain the time evolution of doublets, triplets,..., etc. from singlets. The experiments of reference [2] on the coagulation of singlets of hard polystyrene and soft polyvinyl acetate latexes, interpreted in terms of the same theory, confirm the theory in several ways: (a) the theoretical plots of time evolution of singlets, doublets and triplets fit the experimental points, (b) the maximum on the doublet plot is at the predicted value of 1.2 halflives, (c) the doublet plot becomes equal to the singlet plot at halflife 3, (d) the plot »reciprocal singlet fraction vs. reciprocal time« is linear, (e) von Smoluchowski’s theoretical plot cannot be fitted to the experimental points, (D the halflife values obtained by the application of Smoluchowski’s theory in reference [2] are unacceptable because the singlet fraction, yi, is not reduced to 0.5, but to 0.2-0.3.
