摘要： A process for producing a light color high softening point hydrocarbon resin, which comprises polymerizing an oil fraction obtained by condensing a fractionated component withdrawn in a gas phase from a recovery section of a fractionating tower located below the feeding section and above the bottom of the tower during the fractional distillation in the tower of a feed oil fraction having a boiling point within a range of from 140.degree. to 280.degree. C. selected among cracked oil fractions obtained by thermal cracking of petroleum.
