The structure development and mechanical properties of blow extruded polypropylene containing b-phase nucleating additives was studied. Quinacridone red and cadmium red were both found to nucleate the b phase in polypropylene, the former being a much more efficient nucleator than the latter. The b-p

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

The solubilities of many additives (anti-oxidants, peroxide decomposers, u.v.-stabilizers etc.) in atactic and isotactic polypropylene were studied by an optical method in the range 70-200 °. The additives can be grouped in three categories: (1) Highly soluble (more than 10 wt% at 200°); (2) Moderat

The effect of including 0.5 wt % talc on the photodegradation behavior of polypropylene (PP) was investigated in injection-molded samples exposed to ultraviolet radiation (UV) in the laboratory for periods of up to 24 weeks. The structure of the talc-nucleated samples was characterized by X-ray diff
