N2 - The title oligomers are obtainable by reacting a compd. contg. hydroxyaryl comprising >=3 hydroxyaryl groups 2-R2,4-R1,6-R3-C6H3OH (R1 = an arom., aliph. or cycloaliph. group contg. 1-50 C atoms, R2, R3 = H or an arom., aliph. or cycloaliph. group contg. 1-50 C atoms, or 2 of the R1, R2 or R3 groups together constitute a ring structure contg. 4-50 C atoms) with a polyphenylene oxide in the presence of a catalyst complex comprising a transition metal and amine. Hydroxy-terminal polyoxyphenylene [no.-av. mol. wt. (Mn) 8200] and tert-butylcalix(8)arene were mixed in CCl4 in the presence of CuCl2 and dimethylaminopyridine, bubbling through O:N mixt. for 40 h at room temp. to give an oligomer having Mn 11,590
