Abstract
A thermoplastic composition having an improved impact modifier is described. In an admixture of polyphenylene ether and butadiene-modified alkenyl aromatic resin, a resin which is a network polymer combining poly-alkenyl aromatic and polybutadiene membrane is employed. On subjection to high shear, the continuous membrane phase is shredded into discrete segments which impart an increased impact strength to the composition.
