β-Polypropylene (PP) blends were prepared with supported β-nucleator nucleated PP and PS

ABS
respectively. The β-nucleation
crystallization behavior
melting characteristic and β-crystal content were investigated by DSC and WAXD. It was observed that the crystallization temperatures of β-nucleated PP slightly decreased with increasing styrenic polymers content
especially ABS. Addition of styrenic polymers had no influence on melting characteristic of β-nucleated PP, and three melting peaks were observed. Although the content of β-crystal in β-nucleated PP blends slightly decreased with increasing styrenic polymers content
β-PP blends were obtained with β-crystal content above 80%.
