Abstract
The ethylene polymerization process using constrained geometry catalyst CpSiH2-NH-TiCl2 (CGC) was investigated by ultra accelerated quantum chemical molecular dynamics (UA-QCMD). We observed that the co catalyst MAO reacted with Ti CGC and forms ion pair within 85 fs. With the coordination of ethylene monomer the MAO-CGC ion pair dissociated and once the initial ethylene insertion has taken place, the further ethylene insertion occurring with a less energy barrier, is in good agreement with experimental findings.
