摘要：
Lamellar crystal organization and spherulite formation were investigated as functions of melt polymer concentration and isothermal crystallization temperature for the model eutectic-forming system isotactic polypropylene (iPP) and hexamethylbenzene. Permanganic etching and scanning electron microscopy were used to reveal iPP crystal features. The results were interpreted in terms of the kinetics of crystallization events during thermally induced phase separation of this system.
