Dienes Polymerisation Kinetics with Catalyst Formation in Turbulent Flows

2 Dienes Polymerisation Kinetics with Catalyst Formation in Turbulent Flows [Pg.151]

Therefore, the opportunity of preparing heterogeneous catalysts on the basis of TiC -A1(/-C4H9)3 and VOCl3-Al(f-C4H9)3, in a tubular diffuser-confusor prereactor operating in the turbulent mode, is a flexible way to control the isoprene polymerisation rate and reduce the catalyst consumption. [Pg.154]

The change of reaction rate is well known to change with the intensity of mixing, indicating that elementary stages of the process are diffusion controlled. Preliminary turbulent mode mixing of a reaction mixture, for isoprene and butadiene polymerisation with a microheterogeneous titanium catalytic system, decreases the diffusion limitations when the surface structure of the catalyst is formed. [Pg.155]

An increase of the AC concentration should result in the change of the average MW of polybutadiene according to the diene polymerisation kinetic chart this assumption is confirmed by obtained experimental data. [Pg.155]
