Process for producing a rubber-elastic block copolymer from DOLLAR A at least one block A, which is built up from vinyl aromatic monomers and forms a hard phase, DOLLAR A and / or DOLLAR A at least one block B, which is built up from diene monomers and forms a rubber-elastic soft phase, DOLLAR A and DOLLAR A at least one block B / A, which is built up from vinylaromatic monomers and from diene monomers and forms an (optionally further) rubber-elastic soft phase, DOLLAR A, the glass transition temperature T¶g¶ of block A above 25 ° C. and that of block B / A is below 25 ° C., DOLLAR A, the monomers being polymerized using at least one radical polymerization initiator. |
