摘要：

The model theory on kinetics mechanism of crosslinking copolymerization of stryene (St) with divinylbenzene (DVB) was verified by static and dynamic laser light scattering techniques. The exponential propagation rule of R-g, 14, i.e. R-h=5.195 exp(0.872t) was observed, which agrees well with the model thory of the reaction controlled mechanism before gel point.. Furthermore, from the point of view of the fractal with D-f=1,597, and discussions, the reaction. controlled mechanism was also confirmed. A new way based on modern techenique and novel theory for studying reaction mechanism has also been suggested.
