ABSTRACT:
The production of foamed articles of polyphenylene ether resins is improved by including a modifier comprising an alpha, beta-unsaturated carboxylic acid or derivative. The resulting products are lightweight, exhibit superior heat resistance and retain flame retardancy over polyphenylene ether resins which are foamed in the absence of the modifier. Such resins are especially suited for the production of extrusion and injection foam molding materials.
