Catalytic activity of CpTiCl2(OC6H4Cl-p) supported on the carbonaceous materials modified by nitrogen for the polymerisation of styrene

The catalytic polymerisation of styrene with CpTiCl2(OC6H4Cl-p) catalyst supported on carbonaceous materials characterised by different degree of coalification are reported. The effect of the modification of the support materials by nitrogen on the efficiency of the catalytic system in polymerisation of styrene is analysed. The catalytic activity of the modified carbonaceous materials has been found lower than that of the unmodified material, which can be explained by the nature of the surfaces of the support materials.
