摘要:
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 Tgs, one that is close to the Tg of the pure ETPU, and one that is close to the Tg of the pure PAE. As such, the composite blend retains the properties of the polyarylene ether.
