POLYPHENYLENE OXIDE-RECYCLED POLYSTYRENE COMPOSITION AND METHOD

A polymer composition comprises a melt compounded product of a polyphenylene oxide polymer and a recycled polystyrene material. The recycled polystyrene material exhibits a melt flow index greater than about 25 when devolatized by heating above its glass transition temperature. The polymer compositi...

Beschreibung
Zusammenfassung:	A polymer composition comprises a melt compounded product of a polyphenylene oxide polymer and a recycled polystyrene material. The recycled polystyrene material exhibits a melt flow index greater than about 25 when devolatized by heating above its glass transition temperature. The polymer composition may be in various forms including extruded pellets, extruded foam, and expandable foam beads.
