Nanolignin as Nucleating Agents Promoting Crystallization of Isotactic Polypropylene

Figure 4

(a) and (d) are nonisothermal crystallization curves of iPP and nano-Lig/iPP at different cooling rates, respectively. (b) and (e) are relative crystallinity (X_t) verse temperature during the nonisothermal crystallization process at different cooling rates for iPP and nano-Lig/iPP, respectively. (c) and (f) are the relationship of X_t and time during the nonisothermal crystallization process at different cooling rates for iPP and nano-Lig/iPP, respectively.
