  • Patent number: 8119702
    Abstract: The present invention provides a resin composition consisting of a functionalized polypropylene (PP) and a functionalized styrenic thermoplastic elastomer (TPS). The functionalized PP is a PP grafted with N-vinyl pyrrolidone (NVP) and glycidyl methacrylate (GMA), and the functionalized TPS is a TPS grafted with acrylamide or methacrylamide. The functionalized PP and the functionalized TPS are subjected to melt blending to obtain the resin composition with a slight cross-linking structure due to the reaction between GMA and acrylamide or methacrylamide, therefore the resin composition presents good physical properties. Besides, the resin composition without additional plasticizer or other small molecular organic compounds can be utilized in blood bags, blood transfusion and collection apparatuses, etc. Thus, it does not release small molecular substances which are of potential harm to human body during use.
