The slopes of G″–G′ decreased to 1.21 for the long-chain branched-polypropylene (LCB-PP) and 1.07 for PP-F07-S5. A decreased slope indicates an increase in elasticity, shear thinning effect and melt strength. The extending Avrami analysis proposed by Ozawa applied to PP, LCP-PP and the composite. The exponents were 3.6 for PP, 2.4 for LCB-PP and 1.5 for the composite.
