摘要
The production of a catalyst support (CS) comprises (a) drying a hydrophilic inorganic oxide of a main Gp=II-IV or sub Gp=IV element, or mixtures or mixed oxides thereof, at 110-800 degrees C, (b) optionally reacting free hydroxyl groups in the oxide partly or completely with aluminoxanes (AOX) or aluminium alkyls, and then (c) reacting simultaneously with AOX and polyfunctional organic crosslinkers (PFC). Also claimed are (i) CS obtained by simultaneous crosslinking with AOX and PFC, (ii) supported polyolefin catalysts (SPC) containing reaction products of CS and polyolefin catalyst(s), and (iii) a process for the production of polyolefins by (co)polymerisation of olefins in presence of SPC.
