摘要：
The spherulitic growth rate of isotactic polypropylene in dotriacontane was studied using optical microscopy. Polymer concentration was varied from 100 to 10 wt% iPP in 10 wt% intervals. Crystallization temperature was varied from 372 to 429 K in 1 K intervals. The influence of these variables on polymer spherulitic growth rate and regime transitions was analysed using the Lauritzen-Hoffman and Toda nucleation theories.
