Abstract
The sensitivity to stresses and the melt strength of thermoplastic polymer mixtures which comprise a polyphenylene ether and a polyvinyl aromatic compound can be improved by the addition of a polyfunctional dienophilic compound, for example, a bismaleimide or of a polyfunctional conjugated diene compound, for example, divinyl benzene.
