Abstract

The application provides a bimodal polypropylene random copolymer with good response to nucleating agents, increased crystallization temperature, good mechanical and optical properties, as well as low amounts of extractables and good processability in the sense of high Melt Flow Rate. The present invention further relates to articles made thereof, and the use of the bimodal polypropylene random copolymer for specific applications. It also relates to a process for the preparation of said bimodal polypropylene random copolymer.
