ABSTRACT OF THE DISCLOSURE A method for preparing a novel polymer which com- prises polymerizing a polymerizable material selected from the group consisting of (a) substituted or unsubstituted dicyclopenta- diene; (b) a cationically polymerizable unsaturated hydro- carbon-containing fraction obtained by distilling a cracking or reforming product of a petroleum and having a boiling point is the range of -20°C. to 280°C.; (c) a cationically polymerizable vinyl aromatic hydrocarbon having 8 to 10 carbon atoms; (d) a mixture of two or three of ingredients (a), (b) and (c); and (e) a mixture of any one of ingredients (a) to (d) with a cationically polymerizable unsaturated aliphatic hydrocarbon having 4 to 10 carbon atoms in the presence of a cationic polymerization catalyst; wherein a high-boiling product having a boiling point of at least about 150°C. and an oxygen content of at least 0.5% by weight is introduced into the polymerization system at any stage of the polymerization process or into the resulting polymer. the said high-boiling product being obtained as a by-product in a process comprising oxidizing a benzene or naphthalene ring-substituted with at least one isopropyl group to convert it to the corresponding hydroperoxide and then decomposing it with an acid to produce the corresponding phenol or naphthol. The polymer obtained by this method is useful as a substitute for a tar resin in a tar-containing resin com- position, such as a tar epoxy resin composition or a tar urethane resin composition.
