1. A graft polymer having a weight average molecular weight of from 5 000 to 2 000 000, which consists of structural units of the general formula (I) see diagramm : EP0156990,P9,F1 and whose main chain is composed of polymer units see diagramm : EP0156990,P9,F2 and whose side chain -X-PPE is composed of units of a grafted polymer, in which formulae A is a polymerized vinyl-aromatic unit ; B is a polymerized organic unit bearing an ether side group and derived from a monoolefinically unsaturated monomer containing OH groups ; C is a polymerized unit of a mono-or diolefinically unsaturated monomer which does not contain an OH group and is copolymerizable whth the monomers on which A and B are based, units A, B and C being distributed randomly, alternately and/or as blocks in the main chain ; m and n are each an integer from 1 to 3 or larger than 3, it being possible for n to also be 0 if B is derived from a vinyl-aromatic monomer containing OH groups ; p is an integer from 0 to 3 or larger than 3 ; X is the radical of a bifunctional coupling agent which is derived from a bifunctional organic or inorganic acid derivative or from an alkyl chlorosilane ; and PPE is a substituted or unsubstituted polyphenylene ether radical attached via a terminal oxygen atom.
