J. Zuo et al., AN ANALYSIS OF FRACTAL GEOMETRY OF MACROMOLECULAR GELATION, Science in China. Series B, Chemistry, life sciences & earth sciences, 39(5), 1996, pp. 468-476
With fractal geometry theory and based on experiments, an analysis of
fractal geometry behavior of gelation of macromolecules was carried ou
t. Using the cross-linking copolymerization of styrene-divinylbenzene
(DVB) as an example, through the determinations of the evolution of th
e molecular weight, size and the dependence of scattering intensity on
the angle of macromolecules by employing laser and synchrotron small
angle X-ray scattering, respectively, this chemical reaction was descr
ibed quantitatively, its fractal behavior was analyzed and the fractal
dimension was also measured. By avoiding the complex theories on gela
tion, this approach is based on modern physical techniques and theorie
s to perform the analysis of the behavior of fractal geometry of macro
molecular gelation and thus is able to reveal the rules of this kind o
f complicated gelation more essentially and profoundly.
