Isothermal crystallization of isotactic polypropylene in dotriacontane. III. Effect of dilution and crystallization temperature on growth rate

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 po...

description 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.
