Abstract:
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 Rg, i.e. Rh=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 Df=1.597,and discussions, the reaction controlled mechanism was also confirmed. A new way based on modern technique and novel theory for studying reaction mechanism has also been suggested.
Key words: Gelation, Reaction control, Diffusion control, St-DVB
