摘要

This paper presents data on difencholate of titanocene, new organotitanium coordination compound and its application to a polymerisation of styrene. The new complex was characterised by ~1H and ~13C NMR spectroscopy and mass-spectrometry. The polymerisation of styrene was realised in tightly closed Schlenk tubes under dry N_2 atmosphere in the presence of methylaluminoxane as co-catalyst, providing the necessary [Al]/[Ti] ratio of 4000. The samples of the polystyrene obtained having syndiotatic configuration structure were analysed by a set of different modern physico-chemical methods: get-permeation chromatography, Fourrier transform IR-spectroscopy and differential scanning calorimetry.
