Epoxy resin composition
First Claim
1. An epoxy resin composition comprising(A) a novel copolymer produced by polymerizing a polymerizable material selected from the group consisting of(a) substituted or unsubstituted dicyclopentadiene,(b) a cationically polymerizable unsaturated hydrocarbon-containing fraction obtained by distilling a cracking or reforming product of a petroleum and having a boiling point in 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 atomsin the presence of a cationic polymerization catalyst with 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 being 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 residue, comprising a mixture of by-products, in a process comprising oxidizing a benzene or naphthalene ring-substituted with at least one isopropyl group to convert it to the corresponding hydroperoxide, decomposing the hydroperoxide with an acid to produce the corresponding phenol or naphthol, and separating the phenol or naphthol from the resultant reaction mixture to obtain said residue comprising a mixture of said by-products;
(B) a polyepoxy compound; and
(C) a curing agent.

Abstract
An epoxy resin composition comprising
[A] a novel copolymer produced by polymerizing a polymerizable material selected from the group consisting of
(a) substituted or unsubstituted dicyclopentadiene;
(b) a cationically polymerizable unsaturated hydrocarbon-containing fraction obtained by distilling a cracking or reforming product of a petroleum and having a boiling point in 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 with 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 being 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;
[B] a polyepoxy compound; and
[C] a curing agent.
This epoxy resin composition is useful for paints, adhesives, road-repairing materials, floor coverings, etc.
