Petroleum resins are produced using a supported BFcocatalyst complex. Preferably the cocatalyst is organic such as an alcohol or a carboxylic acid. Use of the catalyst in supported form together with the cocatalyst enables control over both Bronsted and Lewis acidity leading to better control of resin properties. Waste disposal and catalyst handling problems are also overcome.

Petroleum resins and their production with BF3 catalyst

Petroleum resins are produced using a supported BF cocatalyst complex. Preferably the cocatalyst is organic such as an alcohol or a carboxylic acid. Use of the catalyst in supported form together with the cocatalyst enables control over both Bronsted and Lewis acidity leading to better control of resin properties. Waste disposal and catalyst handling problems are also overcome.

Petroleum resins are produced by using a supported halide based Lewis acid polymerization catalyst wherein the Lewis acid is chemically bound to the support and free hydrogen halide and/or alkane formed by the reaction of the Lewis acid with the support has been removed. The more active catalysts are useful with both pure monomer and mixed feeds.
