| titleOfInvention |
Process for the production of petroleum resins of varying softening points |
| abstract |
A petroleum resin feedstock comprises a C5 stream distilled from a cracked petroleum fraction to which has been added butadiene raffinate which comprises isobutene, butenes-1 and -2 and butanes and which is what remains of a C4 fraction after removal of butadiene. The feedstock may be polymerised to a petroleum resin by means of a Friedel Crafts catalyst. |
