Abstract: Blokové kopolymery obsahují alespon dva tvrdé bloky S.sub.1.n. a S.sub.2.n. z vinylaromatických monomeru a alespon jeden mezi nimi ležící statistickýmekký blok B/S z vinylaromatických monomeru a dienu. Podíl tvrdých bloku ciní pres 40 % hmotn., vztaženo na celý blokový kopolymer. Zpusob výroby spocívá v tom, že se blokové kopolymery vytvárí sekvencní aniontovou polymerizací, pricemž se polymerizace mekkého bloku (B/S) provádí v prítomnosti draselné soli. Blokové kopolymery nebo polymerové smesi se používají k výrobe vláken, fólií a tvarových teles.

Abstract: In a block copolymer (I) containing at least two hard blocks (S1, S2) prepared from a vinylaromatic monomer (M1) and, between them, at least one soft block (BS) prepared from M1 and a diene (M2), the proportion of hard blocks is over 40 wt.% of total (I). Independent claims are also included for the following: (a) mixtures of (I) and additional styrene polymers; and (b) preparation of (I) by sequential anionic polymerization, with at least polymerization of BS being in presence of a potassium salt.
