Controlled RAFT polymerisation was used to prepare polymer–drug carriers based on HPMA copolymers, showing well-defined structure with narrow molecular weight distribution. The anticancer drug doxorubicin was bound to the polymeric carrier by hydrazone bond enabling pH-controlled release. RAFT polymerisation facilitated the synthesis of semitelechelic copolymers, which were used in the synthesis of monoclonal anti-CD20 antibody–polymer–drug conjugate and reductively degradable high-molecular-weight graft polymer–drug conjugate, designed for active or passive tumour targeting.
