Abstract
Blends of high molecular weight polyphenylene ethers with various epoxy materials, particularly polyglycidyl ethers of bisphenolic compounds, are homogeneous at high temperatures and may be cured in the presence of a catalyst such as aluminum tris(acetylacetonate) or zinc bis(acetylacetonate), especially in the additional presence of an accelerator such as a basic nitrogen compound. The cured compositions have advantageous physical and electrical properties and are useful, for example, for the preparation of printed circuit boards.
