ABSTRACT:
There are provided plasticized thermoplastic compositions useful for molding which comprise a polyphenylene ether resin, a plasticizer, a mineral reinforcing agent, e.g., aluminum silicate, titanium dioxide, zinc oxide, antimony oxide, and the like, and optionally, an impact modifier. The compositions possess improved stiffness properties with unexpectedly significant retention of ductility in comparison with corresponding compositions which do not contain the mineral reinforcing agent.
