To overcome PLLA�s poor crystallization capability, using nucleating agent as improvement strategy was performed in this study. PPAPH an organic firstly synthesized, and then PLLA blended with different loading through melting blend method, the resulting influences of on performances were investigated relevant testing instruments. Melt-crystallization revealed that played important role promoting providing effective sites heterogeneous nucleation, effect melt-crystallization very poor, indicating low could cause to possess powerful capacity. In addition, relative final temperature beneficial for PLLA/PPAPH�s crystallization. However, increase cooling rate during stage weakened cold-crystallization suggested had inhibition process some extent. Melting behaviors depended heating previous including at various rates isothermal temperatures. enhanced fluidity, tensile modulus strength. Unfortunately, transmittance seriously increased, well elongation break continuously decreased.
