Structures and Properties of PA6/PP/SBS Blends Prepared by Pan-milling

Abstract

Abstract: Anovel technique to modify the morphology and thus to enhance the mechanical properties of polyamide 6(PA6)/polypropene(PP)/styrene-butadiene-styrene triblock copolymer(SBS) blends was reported. Ultra fine PA6 and PPparticles were prepared by using the pan type milling equipment and were mixed with SBSto produce blends. The phase structure of the blends was studied with TEMand the mechanical properties of the blends processed at different temperatures were also investigated. The PA6 PPco powder prepared by pan milling shows the improved compatibility and interfacial action with SBS. When the addition of PA6/PPwas 4%～8%, the tensile strength of the blends was enhanced greatly and the elongation at break changed little. With the variation of the processing temperature, phase structure of PA6/PPchanged remarkably and the PPparticles adhered to form chain structure and the performances of the blends were further promoted.

Key words: Pan milling, Ultra fine particle, PA6, PP, SBS
