Abstract

A non-water-white resin obtained by polymerizing a steam-cracked petroleum naphtha fraction boiling within the range 50-450 DEG F., and from which all the C4 hydrocarbons have been removed, is hydrogenated under such conditions that the colour is decreased towards water-white. A typical fraction comprises aliphatic mono- and diolefins (including cyclic), benzene, toluene, higher aromatic hydrocarbons and paraffins. Hydrogenation is preferably carried out in solution in a volatile solvent at 100-750 DEG F. under a pressure of 100-5000 p.s.i.g. using reduced nickel as catalyst. The polymer resin may be steam-stripped to remove all volatile constituents before hydrogenation. Polymerization may be effected by using clay or a Friedel-Crafts catalyst, or in two stages, using first clay and then a Friedel-Crafts catalyst. It is preferred to remove cyclopentadiene and its lower alkyl homologues before polymerization, preferably by heat soaking to dimerize and distilling to leave the cyclopentadienes as residue.
