Abstract: Polyphenylene ether (PPE) macromonomers have been commercially available for years for use in in electronic circuit material applications. Typical processing of this high Tg solid involves solvent based dissolution and incorporation into the formulation. However, there are challenges with processability in typical non-solvent processes such as hotmelt composite laminates, adhesives, and coatings. Epoxidized PPE macromonomers provide lower viscosity products that can be produced through standard methods such as direct epoxidation or reacting with diepoxide-based reactive diluents. In this paper, we will study the adduct method due to its relative simplicity. Various ratios of PPE macromonomer and types of reactive diluent were studied. Cured thermoset compositions using these adducts can demonstrate improved toughness compared to compositions of conventional epoxies. Electrical laminates of PPE-DGE and PPE epoxy adducts can demonstrate low Dk and Df, V0 rating on UL94 vertical burn test and a successful solder float test.
