Abstract: This invention provides a new dicyclopentadiene phenol and 2,6-dimethyl phenol copolymer epoxy resin with excellent heat resistance, low dielectric constant Dk, low dissipation factor Df having the formula 1. Preparation of dicyclopentadiene phenol and 2,6-dimethyl phenol copolymer epoxy resin in two steps: Step 1, reacting (a1) dicyclopentadiene phenol resin represented by formula 2 with (a2) 2,6-dimethyl phenol in the presence of acid catalyst by (a3) aldehyde compounds to synthesize dicyclopentadiene phenol-2,6-dimethyl phenol copolymer, and Step 2, reacting dicyclopentadiene phenol and 2,6-dimethyl phenol copolymer with excess epichlorhydrin under NaOH condition to prepare dicyclopentadiene phenol and 2,6-dimethyl phenol copolymer epoxy resin. When this dicyclopentadiene phenol and 2,6-dimethyl phenol copolymer epoxy resin according to the present invention is substituted into compositions for laminate, they have low dielectric constant, low dissipation factor, and no delamination after longer than 10 minutes 288° C. soldering test and 2 hours pressure cooking test.
