Abstract
The mechanical and thermal properties of B30/iPP, B30/sPS and sPS/iPP/B30 blends were investigated by unnotched izod impact tester, DSC and tensile strength tester. The results showed that the mechanical properties of B30/iPP, B30/sPS and sPS/iPP/B30 blends were better than that of homopolymer B30 and sPS. The blend of sPS/B30 with the ratio of 80/20, unnotched izod impact strength was 41.2 KJ/m2, tensile strength 32.5 MPa. The blend of B30/iPP with the ratio of 90 to 10, the unnotched izod impact strength was 46.2 KJ/m2 and the tensile strength 27.2 MPa; and the blend of sPS/iPP/B30 with the ratio of 90/10/10, the unnotched izod impact strength was 42.3 KJ/m2, and the tensile strength 33.7 MPa. DSC result showed that in the blend system of B30/iPP and sPS/iPP/B30 the iPP-Tg region shifted toward the sPS-Tg. However, the sPS-Tg shifted inward slightly.
