Tailoring material properties like mechanical deformation behavior is of special interest for possible applications. Isotactic Polypropylene (iPP) is a low-cost polymer, showing a high modulus with the drawback of being brittle. By blending commercial available iPP with high molecular iPP (synthesized with metallocene catalysts) we intended to influence material properties like failure behavior, such broadening the range of accessible applications. This approach additionally has special advantages in the recycling process since there is no mixture of chemical different materials. We will present the results of different blending experiments, analyzed by DSC and mechanical measurements. For a target-oriented approach to tailoring material properties it is crucial to know the processes taking place on a microscopic level like crystallization. Preliminary results of measurements with AFM and X-ray scattering and their connection to the macroscopic behavior will be discussed.
