An irradiated petroleum resin and its preparation are described. In an example, a gas-oil distillate (b.p. 200 to 400 deg C) obtained by steam-cracking was distilled, and the 20 deg to 135 deg C fraction was heated 6 hours at 125 deg C to dimerize the cyclopentadienes. This product was 18% C/sub 6/H/sub 6/, 7% C/sub 6/H/sub 6/CH/sub 3/, <1% C/sub 8/ aromatics, 15% diolefins, 59% olefins and 1% paraffins by weight. After adding 1 wt.% AlCl/sub 3/ catalyst the mixture was polymerized at 30 deg C, the polymer was separated, melted, mixed with divinyl benzene, and irradiated 87 hr at 335,000 R/hr. This final product did not melt at 220 deg C and was largely insoluble in n-heptane. (T.R.H.)
