Abstract

Blends of polyarylene ether resins and anionically-polymerized monovinylidene aromatic compounds having a molecular weight distribution not greater than 1.8 are characterized by a lowered melt viscosity without significant loss in mechanical properties. The incorporation of elastomeric toughening agents does not significantly negatively affect processability or other properties of the blends.
