Petroleum resins and their production with BF3 catalyst

   
   

Petroleum resins are produced using a supported BF.sub.3 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.

El uso del catalizador en forma apoyada junto con el cocatalyst permite control sobre la acidez de Bronsted y de Lewis que conduce para mejorar el control de las características de la resina. La disposición inútil y el catalizador que manejan problemas también se superan.
