ABSTRACT:
A process for preparing a resin suitable for preparation of sizes, which comprises polymerizing a cracked oil fraction which is obtained by the thermal cracking of petroleums, has a boiling point of 20.degree. to 220.degree.C., and contains diolefins, thereby to form a hydrocarbon resin, reacting the resulting hydrocarbon resin with an unsaturated dicarboxylic acid or its anhydride, and heating the acid-modified resin in the presence of water or an alkali metal hydroxide at a temperature of 130.degree. to 350.degree.C.
