Abstract:
ABS/iPP composites were prepared by extrusion processing and its crystallization, mechanical properties were studied. The result of WAXD showed that β-modification was induced with the help of ABS along β(300) lattice pland, and α-modification was restrained. When the content of ABS was 5wt%, the relative content of β-crystal in iPP was 0.45, and the crystallinity was 66.94%. The results also showed that the relative content of β-crystal was hard to increase continually, because the crystalline rate was too fast for iPP chain segment to adjust its chirality to form β-crystal. It was found from DSC that the crystalline temperature and rate of iPP was increased with the adding of ABS, and the melting peak of β-crystal was appeared in the melting curve of ABS/iPP composites. It was observed in POM figures that β-crystal of iPP chain segment was crystallized belong ABS chain segment. In addition, the mechanical properties and heat distortion temperature were increased. In conclusion, ABS can be used as polymeric β-nucleating agent for inducing iPP into β-modification and improving the properties of iPP.
