## Abstract Nucleation characteristics of isotactic polypropylene (iPP) nucleated by the Ξ±/Ξ² compounded nucleating agents (NAs) were investigated by wideβangle Xβray scattering, differential scanning calorimetry and mechanical testing. The results showed that the nucleation effect of the Ξ±/Ξ² compou

The influence of isotacticity, ethylene comonomer content, and nucleating agent additions on the structure and properties of melt-spun polypropylene filaments was studied for a series of polypropylenes having similar resin melt flow rates (MFR z 35), average molecular weights, and polydispersities.
The isothermal and nonisothermal crystallization kinetics of nonnucleated and nucleated isotactic polypropylene ( iPP ) were investigated by DSC and a polarized light microscope with a hot stage. Dibenzylidene sorbitol ( DBS ) was used as a nucleating agent. It was found that the crystallization rat
