Abstract: A novel sulfonated poly (phthalazinone ether sulfone ketone) resin catalyst (S-PPESK) was prepared by means of sulfonation method and characterized with titration. The catalytic activity of this new resin catalyst in the isobutene oligomerization was measured in detail; it exhibited good catalytic activity and excellent isobutene dimerization selectivity. The results indicated that when the sulfonation degree (S.D.) of the catalyst increased, i.e. the acid volume of the catalyst increased, the conversion for isobutene and the selectivity for trimer increased also, while the selectivity for dimer decreased, and the selectivity for tetramer was almost unchanged.

Key words: S-PPESK, Sulfonation degree (S.D.), Catalytic activity, Isobutene oligomerization
