Propylene-based compositions of enhanced appearance and excellent mold flowability


The present invention relates to a class of impact copolymer polypropylene (icp) compositions exhibiting the advantageous combination of excellent tiger (flow) marking performance in large/long molded parts, very low gels count and exceptional mold flowability (high mfr) despite the high viscosity ratio (e.g., >4) between rubber and propylene based matrix phases. Furthermore, it has been surprisingly found that the inventive compositions are associated with a low gels count even when using a quite coarse mesh wire screen, e.g., 60 mesh wire screen, independent of screw type e.g., twin or single screw.
