Process for preparing a polypropylene-based object having an increased surface energy
The present invention relates to a process for preparing a polypropylene-based object having an increased surface energy, said process comprising the subsequent steps of
a) providing a polypropylene resin,
b) forming an object of said polypropylene resin, and
c) subjecting the surface of the object to a surface energy increasing treatment step,
Characterized in that the polypropylene resin comprises
A) at least one secondary antioxidant of formula (I)
in which
n is 0 or 1,
each R may be the same or different and is an unsubstituted phenyl group or a phenyl group substituted by one or two alkyl groups having from 1 to 12 carbon atoms, and
X is a residue of a monofunctional or difunctional phenyl group, diphenyl group, diphenyl ether group or dibenzofuranyl group
and/or of formula (II)
