Abstract:
Extruded articles based on a nucleated polypropylene homopolymer showing improved optical properties such as haze or relative haze and a good balance between optical and thermomechanical properties.

Claim (Index 13):
A method for producing an extruded article according to  claim 1 , with improved optical properties including haze or relative haze, comprising the steps of:\n a. polymerising propylene and optionally ethylene in the presence of a Ziegler-Natta catalyst, wherein the Ziegler-Natta-catalyst comprises:\n i. compounds of a transition metal of Group 4 to 6 of IUPAC, \n ii. a Group 2 metal compound (MC), \n iii. an internal donor (ID), wherein said internal donor (ID) is a non-phthalic compound, \n iv. a co-catalyst (Co), and \n v. optionally an external donor (ED) \n b. incorporating at least one \u03b1-nucleating agent c. extruding articles comprising said polymer obtained in step a) to b).
