Beschreibung
Zusammenfassung:	Disclosed are a supported catalyst system comprising a substituted 2-hydroxythiophene compound and a support material; and a method of making the supported catalyst system; Also disclosed are a gas phase or slurry phase polymerization process employing the supported catalyst system; and a polyolefin made by the gas phase or slurry phase polymerization process. Also disclosed are the substituted 2-hydroxythiophene compound and a precatalyst comprising the substituted 2-hydroxythiophene compound, a metal atom, and a leaving group. Also disclosed are methods of making the precatalyst and the substituted 2-hydroxythiophene compound. Sont divulgués un système de catalyseur supporté comprenant un composé de 2-hydroxythiophène substitué et un matériau de support ; et un procédé de fabrication du système de catalyseur supporté ; sont divulgués également un procédé de polymérisation en phase gazeuse ou en suspension épaisse utilisant le système de catalyseur supporté ; et une polyoléfine fabriquée par le procédé de polymérisation en phase gazeuse ou en phase de suspension épaisse. Sont divulgués en outre, un composé 2-hydroxythiophène substitué et un précatalyseur comprenant le composé 2-hydroxythiophène substitué, un atome métallique et un groupe partant. Sont divulgués par ailleurs, des procédés de fabrication du précatalyseur et du composé 2-hydroxythiophène substitué.
