中文摘要	a novel catalyst system based on nickel(ii) tetraphenylporphyrin (ni(ii)tpp) and methylaluminoxane for styrene polymerization was developed. this catalyst system has a high thermal stability and show fairly good activity. the obtained polystyrene (ps) was isotactic-rich atactic polymer by c-13 nmr analysis, and its molecular weight distribution was rather narrow (m-w/m-n approximate to 1.6, by gpc analysis). esr revealed that ni(ii)tpp pi cation radicals were formed in the polymerization and could remain in the resulting ps stably. the mechanism of the polymerization was discussed and a special coordination mechanism was proposed. the ps product containing ni(ii)tpp pi cation radicals can be used as a potential functional material.
