Abstract
A low molecular weight engineering thermoplastic polyurethane (ETPU) can be homogeneously melt blended with a polyarylene ether (PAE) to give a low viscosity melt processable blend, and subsequently cooled to form a heterogeneous dispersion of the ETPU in the PAE that has two T s, one that is close to the T of the pure ETPU, and one that is close to the T of the pure PAE. As such, the composite blend retains the properties of the polyarylene ether.
