A propylene-ethylene copolymer Versify2300 with 12 wt% ethylene content(V-2300) was multi-monomer melt grafted using maleic anhydride and styrene (MAH-St) by extruder.The effect of the addition of Versify-g-(MAH-co-St) (g-V-2300) on the compatibility of PA6/(V-2300+g-V-2300)(70/30) blends was investigated by means of SEM
FTIR and mechanical property measurements.The results showed that with increasing the g-V-2300 content
the size of the V-2300 dispersed phase became smaller and more uniform.Wheng-V-2300 is 25 wt%
the dispersed phase size is only 0.27 μm
and the izod impact strength of the blend is 324.54 J/m and is 16 times larger than that of the blend without g-V-2300.The addition of g-V-2300 remarkably improved the mechanical properties of PA6/(V-2300+g-V-2300)(70/30) blends including elongation
tensile strength and flexural strength.Thus toughened Nylon 6 alloys could be achieved with balanced mechanical properties.
