Crystallization of Polypropylene Induced by the Aqueous Dispersion of Isotactic Polypropylene Wax

Abstract:

The Polarized light microscope and DSC are used to study the influence of the nucleation agents’ type (The aqueous dispersion of isotactic polypropylene wax and the commercial nucleating agent TMB-5), nucleating agents’ content on the β-crystal content, melting points of α-crystal and β-crystal are studied in the paper. The difference of their capacities of inducing the crystallization of polypropylene are compared and analyzed. The foundation of the treatment of the aqueous dispersions of isotactic polypropylene wax on the reinforcements to induce crystallization on the surfaces of the reinforcements is laid.
