The morphology and mechanical properties of PVC/SMA-g-PA6 blends were investigated in this paper. Graft to polymer SMA-g-PA6 was prepared via a solution graft reaction between SMA and PA6. FTIR test evidences the occurrence of the graft reaction between SMA and PA6. DSC analysis shows that SMA-g-PA6 has a lower melting point of 187degreesC, which may result in a decrease in crystallinity of PA6 and thus enable efficient blending of SMA-g-PA6 and PVC. Compatibilization was evidenced by the dramatic increase in mechanical properties, the smaller particle size and finer dispersion of PA6 in PVC matrix, and, further, a cocontinuous morphology at 16 wt% SMA-g-PA6 content. SMA-g-PA6 from the solution graft reaction can toughen and reinforce PVC material.
