Verfahren zur Herstellung von hydrophob-hydrophilen AB-Blockcopolymeren

摘要

The invention relates to a process for the preparation of hydrophobic/ hydrophile AB block copolymers in which block A comprises a monomeric unit, a being a conjugated diene and block B comprises a monomeric unit, b being an epoxide. It also relates to the AB block polymer synthesised by the production process, and micellar systems which are produced from the AB block polymer. According to the invention, synthesis of the AB block polymer occurs in two stages, the first stage being preparation of the block A in an apolar solvent, and the second stage being preparation of the block B in a polar solvent.
