    Abstract: In the prepn. of stabilised polyolefins (I), which have a small fraction extractable with cold heptane, by polymerisation of olefins with Ziegler or Phillips catalysts, (I) is brought into contact with an involatile phenol deriv. (II) immediately after leaving the polymerisation reactor. Also claimed are (I) per se and fibres, films and mouldings contg. (KI). Pref. (II) has a mol.wt. of at least 250 and a b.pt. of over 270 degrees C at 100 kPa. (I) esp. is a 2,6-di-tert.-butylphenol deriv..
