摘要

The copolymers (comb polymers) having mean molecular weights (weight average Mw) of from 10,000 to 2 million, are built up from: A a main chain polymer which makes up from 10 to 90% by weight, based on the copolymer, has a mean molecular weight (Mw) of from 8,000 to 1 million and contains, in polymerised form, a1 at least one vinylaromatic monomer unit and a2 at least one further monomer unit and B one or more side chain polymers, where the side chains make up from 90 to 10% by weight, based on the copolymer, have a mean molecular weight (Mw) of from 2,000 to 1 million and are obtainable by anionic polymerisation of conventional monomers or mixtures of monomers with the aid of alkyllithium compounds and subsequent reaction of the living anion with a chain terminator, wherein, in order to build up polymer A (main chain), the further monomer unit a2 is selected from the group comprising alpha , beta -unsaturated acids, esters, monoesters or imides thereof, and the linking of the main chain polymer A to the side chain polymers B via at least one monomer unit a2 takes place via a functional group formed from the chain terminator. The copolymers are used for blending with other polymers and for production of mouldings.
