Abstract
A minor proportion of a di-vinyl aromatic compound, such as a divinyl benzene or naphthalene, is reacted with a polymerized unsaturated resin under the influence of high-energy ionizing radiation, at a temperature from -10 DEG to 150 DEG C., and a dose rate of at least 0.1 equivalent megaroentgens per hour, until a total dose of at least 1/2 megaroentgens has been received. The reaction may be carried out in solution in a solvent which is inert to radiation such as n-heptane, cyclohexane and benzene. The unsaturated resin is one formed from a mixture of diolefins and olefins and is preferably a petroleum resin made by removing cyclopentadienes from a steam-cracked petroleum distillate fraction and then polymerizing the cyclodiene-free fraction with an aluminium halide catalyst.ALSO:A minor proportion of a di-vinyl aromatic compound, such a divinyl benzene or naphthalene, is reacted with a polymerized unsaturated resin under the influence of high energy ionizing radiation, at a temperature from - 10 DEG to 150 DEG C., and a dose rate of at least 0.1 equivalent megaroentgens per hour, until a total dose of at least 1/2 megaroentgens has been received.

The unsaturated resin is one formed from a mixture of diolefins and olefins and is preferably a petroleum resin made by removing cyclopentadienes from a steam-cracked petroleum distillate fraction and then polymerizing the cyclodiene-free fraction with an aluminium halide catalyst. The treated polymers have increased softening points.
