Title: HIGH FLOW HETEROPHASIC POLYOLEFIN COMPOSITION HAVING IMPROVED STIFFNESS/IMPACT BALANCE
Abstract:
High flow nucleated heterophasic polyolefin compositions comprising a matrix comprising a propylene homo- and/or copolymer and an elastomeric alpha-olefin copolymer phase dispersed in the matrix, which have rather high melt flow rate, improved impact strength but also an excellent impact/stiffness balance and a process for the preparation of such a heterophasic polyolefin composition, articles made therefrom and uses of the heterophasic polyolefin composition.
