Abstract
This invention is concerned with a method for plasticizing polyetherimide polymers with a reactive bisimide plasticizer. This invention also provides novel plasticized polyetherimide blends and rigid polyetherimide blends which are obtained by polymerizing the reactive bisimide plasticizer to form an interpenetrating matrix polymer. The plasticized blends exhibit melt viscosities and glass transition temperatures lower than those associated with the polyetherimide component of the blends. The rigid blends exhibit higher dimensional stability than polyetherimides. The blends produced are suitable for the manufacture of filaments, composites, fibers, films, molding compounds, coatings, etc.
