    Abstract: The invention concerns statistical propylene copolymers in which 0.1-20 wt.% is accounted for by polymerisation-incorporated ethylene and the xylene-soluble components (XL) satisfy the inequation (I) XL >/= 3,8 + 1,2 [C2], in which [C2] represents the proportion by weight of the polymerisation-incorporated ethylene; and the proportion in wt.% of isotactic triads [mm] or isotactic pentads [mmmm] as determined by C nuclear magnetic resonance spectroscopy lies within the range determined by the inequations (IIa) 96.0 wt.% >/= [mm] and (IIb) 94.0 wt.% >/= [mmmm]. The statistical propylene copolymers are suitable for use as foam particles and moulded parts.
