Abstract
Poly(aryl ether sulfones) (PAES) polymers (P1) which are functionalized with reactive functional groups on at least one end of the PAES polymer, a process for preparing the PAES polymers (P1), a process for preparing block copolymers (P2) using the functionalized poly(aryl ether sulfones) (PAES) polymers (P1) and the block copolymers (P2) obtainable by such process
