Talc-filled polypropylene (PP) composites were prepared by extrusion in a wide composition range (0-40 wt %). T o improve the affinity relation between talc and the PP matrix, we modified the talc surface with silane coupling agents. Differential scanning calorimetry investigations on test samples,

The non-isothermal crystallization behaviour of high purity b-phase and a-phase polypropylene (PP) and their calcium carbonate-Γlled composites was investigated by means of di β erential scanning calorimetry. High purity b-PP polymer was prepared by adding an e β ective b-nucleator consisting of equal
## Abstract Steadyβstate and oscillatory shear behavior of three neat syndiotactic polypropylene (sβPP) resins and a sβPP resin (sβPP#8) filled with CaCO~3~ particles of varying content, size, and type of surface modification were investigated. All of the neat sβPP resins investigated exhibited the
