Petroleum resins and their production with BF3 catalyst

James Hanley Clark (Inventor), Maria Leonor Garcia (Inventor), Kenneth Lewtas (Inventor), Karen Wilson (Inventor)

Research output: Patent


Petroleum resins are produced using a supported BF3 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.
