Excellent properties and extrusion foaming behavior of PPC/PS/PTFE composites with an in situ fibrillated PTFE nanofibrillar network

In this work, we compounded polystyrene (PS) and polytetrafluoroethylene (PTFE) with poly(propylene carbonate) (PPC) to prepare multiphase composites that possess special properties and to improve the extrusion foaming ability of PPC.
